The 20 Best Games to 100% in 2026: Ranked by Achievement Satisfaction, Not Just Grind Length

The worst completionist experience isn’t when a game is hard — it’s when the achievement list asks you to repeat something the game already squeezed dry. The 200 fishing quests in Terraria sound like that kind of punishment. In practice, they’re not: each Angler quest sends you to a different biome, often at night, often during events you haven’t triggered yet. Those fishing missions are a backdoor into every system you’d avoid in a normal run.

That distinction — achievements that open the game vs. achievements that pad it — is what separates this list from standard completionist roundups, which are mostly general best-games lists with “easy to 100%” tacked on. Every game here was selected because the achievement design adds something a first playthrough misses.

Twenty games, five types of completionist experience, sorted not by grind length but by whether crossing the finish line actually feels like you learned something. If you’re new to completionist runs, jump to the Starter Pack near the bottom. If you’re already hunting, the comparison table has the data up front.

The 5 Types of Achievement Satisfaction

Not all achievement lists are designed the same way. The games here fall into five categories that predict how satisfying the 100% run will feel:

• Exploration — achievements fire when you find things the base playthrough skips. Every milestone is a discovery.
• Mastery — achievements require demonstrating skills at increasing difficulty. You get better as you progress.
• Narrative — achievements unlock story content distributed across multiple runs. The lore is the reward.
• Unlock Chain — each achievement directly enables the next content unlock. Progress is always visible.
• Map-Clear — spatial completion tracked on an in-game map or checklist. The checklist is the game.

The best completionist games combine two or more types simultaneously. Hollow Knight layers Exploration with Mastery. Hades pairs Narrative with Unlock Chain. Games that feel like a chore — and there are many outside this list — use none of them, asking only for repetition.

All 20 Games at a Glance

Which Completionist Are You?

If you don’t fit one category cleanly: Terraria serves all four. Every achievement type appears in its list — exploration, mastery, collection, narrative side-quests. It’s the one game that justifies all 200+ hours regardless of how you play.

Exploration Completionists: Where Discovery Is the Achievement

These games put content behind genuine exploration. The achievements don’t ask you to repeat what you already did — they surface systems the first run deliberately hides.

1. Terraria — 115 Achievements | 200+ Hours | 0 Missable

Terraria’s achievement design matches its world design: completely open, no linear path, every system interconnected. The 200 Angler quests that sound like the game’s worst grind are actually a structured tour through biomes most players skip — Underground Desert at 3am, Glowing Mushroom biome during Blood Moon. By quest 150, you’ll have encountered a dozen events you’d never triggered in normal play.

The real completion challenge is the Zenith sword. Crafting it requires items from 10 different sword tiers, each from a distinct progression stage, starting from the first Copper Shortsword all the way through to the Terra Blade. The crafting chain forces you to revisit every stage of the game deliberately — it’s archaeology, not grinding. None of Terraria’s 115 achievements are missable, and no playthrough locks you out of anything. See our Terraria Progression Guide 2026 for the full pre-Hardmode to endgame checklist before you start the achievement run.

Skip if: You won’t commit to the Angler quests. The Fisherman’s Pocket Guide — an Angler quest reward — is required for 100%, and there’s no workaround.

2. Hollow Knight — 63 Achievements | 45–60 Hours | 10 Missable

Hollow Knight’s 112% completion system is the best example of achievements designed to teach the game’s geography. Each DLC expansion — Grimm Troupe, Godmaster, Lifeblood — adds achievements requiring you to engage with mechanics the base game only introduces. You cannot finish the Pantheon of Hallownest without mastering every boss across the base game and all three DLC campaigns.

Ten achievements are missable, including Neglect (leaving Zote to die in Greenpath) and Purity (killing the Nailsmith after upgrading the Pure Nail). Plan these on a separate save. The hardest achievement — Steel Heart — requires reaching 112% completion without dying once. Based on community reports, this typically demands at least 10–15 dedicated attempts after you already know the full route. [Tier 4]

Skip if: The Absolute Radiance no-death requirement in Pantheon 5 will end most attempts. If boss mastery isn’t the point for you, Hollow Knight’s 100% will stay perpetually at 99%.

3. Stardew Valley — 40+ Achievements | 80–120 Hours | Route-Split Missable

Stardew’s completionist hook is the Perfection tracker (added in version 1.5), which shows your exact percentage across 21 categories: Shipping, Crafting (148 unique items), Cooking, Fishing, Friendships, Skull Cavern, Golden Walnuts on Ginger Island, and more. Unlike most games where 100% is binary, Stardew makes partial progress visible at all times — you always know precisely what’s left.

The meaningful completionist choice comes early: the Community Center route and Joja Corp route produce mutually exclusive achievements in the same save. Community Center teaches more systems and unlocks more content. The permanent early decisions — farm type, skill profession forks at levels 5 and 10, Mushroom vs. Fruit Bat cave — all affect what’s available in year two and beyond, so planning before year one starts is worth the time.

Skip if: You want a tight run. Stardew’s completion unfolds across multiple in-game years by design, and the Joja route locks you out of Local Legend in that save permanently.

4. Tunic — ~30 Achievements | 12–20 Hours | 2 Missable

Tunic’s achievement design is built around its central secret: the game has its own written language, documented in a manual you assemble page by page throughout the campaign. Collecting all 55 manual pages unlocks the “Thank You For Playing” achievement — both a narrative milestone and a gameplay revelation, since the manual teaches mechanics the game never explains through conventional tutorials. The 20 fairies (each hidden behind an environmental puzzle) and 12 secret treasures form a parallel completion track that rewards reading the environment rather than following a path.

Only 2 achievements are missable; the rest unlock organically. At 12–20 hours, Tunic delivers more discovery per hour than anything else in the Exploration category.

Skip if: You want combat depth over puzzle depth. Tunic’s completion is a secret-hunting exercise, not a skill certification.

Mastery Completionists: Getting Better Is the Entire Point

These games use achievements as a difficulty ladder. Each tier proves you’ve internalized the previous one. If you find yourself checking a wiki before attempting, that’s usually the wrong approach — mastery-type games teach the required skill through the attempt itself.

5. Celeste — 25 Achievements | 25–300+ Hours | 0 Missable

Celeste’s achievement structure is the most elegantly tiered on this list. The base game asks you to collect 175 strawberries — achievable with moderate platforming skill. The B-sides ask you to master remixed versions of each chapter. The C-sides compress each chapter into a sub-3-minute challenge run. Farewell (free DLC) pushes skill to near-expert territory across an extended final sequence.

The 26 Golden Strawberries — requiring a no-death clear of each chapter — sit technically beyond Steam’s 100% threshold, but the community treats them as the real completion ceiling. Steam achievements only: 25–40 hours. Full Celeste as designed by the developers: factor in months for the hardest C-side and Farewell clears. [Tier 3, community consensus]

Skip if: The jump from B-side to C-side represents a competence gap that not every player will close through practice alone. If C-sides feel impossible after three dedicated sessions, the Golden Strawberries certainly will.

6. Neon White — 44 Achievements | 25–30 Hours | 0 Missable

Neon White achieves something rare: the gift system turns social completion into a parallel track alongside speedrunning. Getting platinum on all levels requires finding hidden shortcuts — not just repeating the obvious route. The 97 total gifts across the main campaign unlock character story scenes, distributing a visual novel across the completion process so that mechanical skill and narrative reward arrive together.

No missables, 25–30 hours, and the true ending gates behind gift completion (maxing all social links) rather than a mechanical skill check — making this the most accessible mastery-category game for players who want the full experience without gauntlet-style boss sequences. [Tier 4]

Skip if: You want systemic depth after finishing. Neon White is tight and styled, but once you’ve found every optimal route, there’s little left to discover.

7. Cuphead — 37 Achievements | 20–30 Hours | 0 Missable

Cuphead’s Expert mode achievements are the clearest expression of mastery-gated completion on this list: you cannot check these off without genuinely reading every boss pattern. No-hit runs become possible on Expert after enough repetition — not because you get lucky, but because the hand-drawn animation makes every attack readable once you’ve logged the hours. The game rewards the moment you stop guessing and start anticipating.

Skip if: You’re a casual completionist. Cuphead has no difficulty scaling for completion purposes — Expert is Expert, and the achievement list doesn’t compromise on that.

8. Sekiro: Shadows Die Twice — 35 Achievements | 40–60 Hours | Yes (4 Endings)

Sekiro’s achievements are built around four distinct endings that require different decisions at the same story branch points. The “Return” (true) ending requires finding the Purifying Incense and making specific dialogue choices most players miss on a first run. All four endings can be reached from a single preserved branching save point — multiple full playthroughs aren’t required if you plan the split correctly.

Skip if: You want to fight defensively. Sekiro’s posture/deathblow system is the core mechanic the mastery achievements test — blocking and turtling stalls every boss encounter and every completion milestone with it.

Narrative Completionists: Story Rewards the Persistent

These games distribute their best writing behind completion milestones. A single playthrough recovers 20–40% of what’s actually there. The achievement list and the lore delivery system are the same thing.

9. Hades — 49 Achievements | 50–100 Hours | 0 Missable

Hades’ achievement structure maps directly onto Supergiant’s narrative delivery system. Every run adds new dialogue, relationship developments, and lore fragments. “Friends Forever” — requiring you to max 25 Keepsakes through approximately 1,875 combined encounters — is the game’s relationship-completion marker, and the story closes properly only after hundreds of conversations accumulate across dozens of weapons and builds.

The hardest achievement, “Skelly’s Last Lamentations,” requires a Heat 16 clear — stacking difficulty modifiers from the Pact of Punishment system. Unlike Celeste’s Golden Strawberries, this is achievable for most dedicated players within 60–80 hours. God Mode (toggleable 20–80% damage reduction) is available throughout without blocking any achievement — making Hades the most accessible difficult-game completionist experience on the list. No missables at any point. [Tier 3, PowerPyx]

Skip if: You dislike roguelites. Hades’ completion is inseparable from its run structure — there’s no shortcut to the conversations.

10. Undertale — 16 Achievements | 15–25 Hours | Routing Required

Undertale’s 16 Steam achievements understate what actual completion requires. True completionism means three fundamentally different routes — Normal, True Pacifist, and Genocide — each of which permanently alters what subsequent runs show you. These aren’t difficulty variants; they’re different games with different endings, different boss behaviors, and different narrative interpretations of the same events.

“Don’t you have anything BETTER to do?” requires all 93 Neutral route variations plus True Pacifist and Genocide in a single save file. Community-verified at 40+ hours for full achievement hunting when accounting for every Neutral branch. [Tier 4]

Skip if: The Genocide route’s ethical framing — the game explicitly judges you for completing it and alters future playthroughs accordingly — will remove the enjoyment. The achievement exists. The cost is part of the design.

11. Disco Elysium — 27 Achievements | 40–60 Hours | Yes (Build-Dependent)

Disco Elysium’s achievements track skill check passes, ideological alignment choices, and specific NPC interactions locked to your stat build and dialogue timing. Two playthroughs — one focused on physical/manual skills, one on intellect/perception — cover most of the achievement list. The completionist reward isn’t the checkboxes: it’s discovering that the same murder case reads completely differently through different investigator archetypes. The detective who solves it through empathy and the one who solves it through sheer machismo are nearly different characters.

Skip if: You want combat. Disco Elysium has none, and the achievement list reflects that entirely.

12. Baldur’s Gate 3 — 54 Achievements | 150–500+ Hours | Yes (Multiple)

BG3’s 54 achievements require playing the game the way it was designed — multiple times, with fundamentally different choices. “Leave No One Behind” (save every tiefling refugee), “She Cannot Be Caged!” (rescue a specific character from three separate locations in one run), and the Honor Mode achievement all require deliberate planning on separate saves with incompatible outcomes. Three to five full playthroughs is the realistic path.

The community benchmark for optimised completion is approximately 437 hours; less-focused approaches often reach 800 hours or more. That range isn’t inefficiency — it’s the scale of what BG3 actually contains across origin characters and story branches. [Tier 3, community consensus]

Skip if: You have a single-playthrough mentality. BG3’s design intentionally prevents any one run from unlocking everything — and the achievement list is built around that structure.

Unlock Chain: Every Achievement Opens the Next Door

Unlock chain games make completionist progress immediately visible. Every achievement you earn changes what’s available in the next session. There’s no “collecting for later” — the reward is the next unlock.

13. Vampire Survivors — 243 Achievements (Steam 100%) | 40–60 Hours | 0 Missable

Vampire Survivors’ achievement design is the cleanest unlock-chain system in gaming. Every character, weapon, stage, and game mode is gated behind a specific achievement condition — unlocking Merchant improves shops; unlocking Exdash enables specific item interactions; unlocking Moongolow opens DLC campaign content. The chain has no dead ends. With 449 total achievements across all DLC (243 required for Steam 100%), the scope is enormous, but each session runs 10–30 minutes and makes visible progress on multiple unlock conditions simultaneously.

Critical note: using in-game “spells” (cheat codes) does not count toward achievements. Original unlock conditions must be completed legitimately, including the grindy ones like Queen Sigma (reach level 99 with all 27 standard characters). [Tier 4, Rogue Ranker]

Skip if: You find bullet-heaven mechanics repetitive after 10 hours. The unlock chain only delivers satisfaction if the core loop holds you.

14. Dead Cells — 108 Achievements | 30–50 Hours | 0 Missable

Dead Cells’ 5 Boss Cell progression is the best-structured difficulty ladder on this list for completionists who want a clear endpoint. Each Boss Cell unlocks the next, adds elite enemy spawns, and raises the item randomness ceiling. By Boss Cell 5, the full weapon pool and upgrade tree is available, and defeating the True Final Boss — gated behind a Boss Cell 5 clear — is a genuine skill certificate. The complete weapon unlock table, filling in every gun and grenade slot, forms the secondary completion goal between Boss Cell runs.

Skip if: You want linear progression. Dead Cells resets to the first biome every run regardless of Boss Cell level — the roguelite structure is non-negotiable for the full 108 achievements.

15. Risk of Rain 2 — 109 Achievements | 50–80 Hours | 0 Missable

Risk of Rain 2’s character unlock challenges are designed as tutorials for each survivor’s playstyle. MUL-T’s unlock (clear the first stage in under 25 seconds) teaches aggression. Acrid’s unlock (clear the Challenge of the Mountain without resetting) teaches patience and build flexibility. Each new survivor reshapes what strategies you can attempt in subsequent runs, creating a positive feedback loop between completion and capability that the other roguelites on this list don’t quite match.

Skip if: You’re avoiding co-op. A small subset of ROR2 achievements require multiplayer sessions and can’t be obtained solo.

16. Slay the Spire — 40+ Achievements | 80–120 Hours | 0 Missable

Slay the Spire’s Ascension system — 20 escalating difficulty levels per character, four characters total — is the completionist ceiling for deck-builders. Seeing every card and relic requires deliberate deck construction across hundreds of runs. The full card collection achievement for each character forces you out of your preferred archetypes and into builds you’d normally skip, which is where most of the learning happens. Ascension 20 with all four characters is reached by fewer than 1% of players per Steam achievement data. [Tier 4, community consensus]

Skip if: You want narrative or visual rewards. Slay the Spire has almost none — the reward is the run itself.

Map-Clear Completionists: When the Checklist Is the Game

These games make completion spatial. Progress is visible on a map, checklist, or in-game tracker. There’s no ambiguity about what’s left — you can see it.

17. Ori and the Will of the Wisps — 37 Achievements | 12–20 Hours | 0 Missable

Ori’s 37 achievements are the most accessible map-clear experience on this list. Lupo, an in-game NPC vendor, sells maps that directly reveal the locations of all spirit shards, energy cells, and life cells — the game literally sells you the checklist mid-playthrough. All 37 achievements unlock through natural exploration when you engage with those maps; none require grinding or multiple playthroughs. The final obstacles are “Shard Hunter” (all 31 spirit shards) and the combat shrine completion — timed combat waves at shrine locations across the map. [Tier 4]

Skip if: You need high-difficulty content. Ori’s mastery ceiling is modest compared to every other game in the Mastery or Unlock Chain categories — it’s designed to be accessible, not punishing.

18. Enter the Gungeon — 100+ Achievements | 60–100 Hours | 0 Missable

Enter the Gungeon’s completion is essentially its full gun and item table — hundreds of weapons and items, each with an unlock condition tied to specific boss kills, room types, or NPC interactions. The Master Round achievement (defeating a boss without taking damage) is the checkpoint separating casual players from completionists, and it’s unavoidable for the full completion path. The Gunslinger unlock — the game’s hardest challenge — requires clearing a boss past the final floor, then finishing the Gunslinger’s own boss sequence in a single run.

Skip if: You won’t pursue the Master Round achievements. They’re required for 100% and can’t be bypassed through any other unlock path.

19. Blasphemous — 30+ Achievements | 25–40 Hours | Yes (NPC Quest-Dependent)

Blasphemous’ True Ending chain is a lore-driven achievement sequence where each unlock adds context to the game’s religious horror setting. Most missable achievements are tied to specific NPC questlines — the Gemino quest line is the most commonly missed, requiring three interactions at precise story points that are easy to walk past. The True Ending reveals backstory that recontextualizes nearly every lore collectible in the base playthrough, making the completion reward narrative rather than mechanical.

Skip if: You want quality-of-life design. Blasphemous prioritizes atmosphere and deliberate backtracking over convenience — the inventory management and traversal design reflect that philosophy throughout.

20. A Short Hike — ~18 Achievements | 3–5 Hours | 0 Missable

A Short Hike is the warm-up completionist game: 3–5 hours, no missables, gentle map-clear satisfaction. It exists on this list because it models what good achievement design looks like at its simplest — every collectible teaches you something about the island, every NPC interaction advances a small story, and the final golden feather feels genuinely earned within a single sitting.

Use it as a reset between long completionist runs or as an introduction for someone who’s never done a 100% run before. It establishes the feeling you’re chasing in every other game on this list, in about the same time as a feature film.

Skip if: You need a significant challenge. A Short Hike is deliberately lightweight — the point is the journey, not the obstacle.

Starter Pack for New Completionists

If you’ve never done a 100% run, start here — in this order:

Step 1: A Short Hike (3–5 hours) — Learn what satisfying completion feels like without the time investment. Finish it in an afternoon. It models map-clear design at its most encouraging.

Step 2: Hades (50–75 hours) — No missables, God Mode is always available without blocking achievements, and the narrative rewards every session. This is the most completionist-friendly medium-length game on the list for players starting out — you can’t lock yourself out of anything, and the story gives you a reason to keep going even when a specific achievement is taking longer than expected.

Step 3: Terraria (200+ hours) — Once you know what achievement satisfaction feels like across short and medium games, Terraria is the full-depth completionist experience that makes everything above feel like preparation. Every system you’ve learned to appreciate in the previous two games exists here at a larger scale, with 115 achievements that never ask you to repeat what you already did.

This progression maps to the three most common achievement types: Map-Clear (A Short Hike) → Narrative/Unlock (Hades) → Exploration (Terraria). You’ll have covered the major experience categories before committing to the 200-hour tier. For more on games built for long solo sessions, see our guide to the Best Solo Games 2026.

Frequently Asked Questions

What’s the most satisfying game to 100% in under 30 hours?
Neon White or Hollow Knight if you already know the game. Neon White’s 25–30 hours is achievable in a focused week with no missables. Hollow Knight can be done in 45–60 hours on a first completion attempt — faster if you’ve played it before. Both deliver milestones that feel skill-earned rather than grind-earned, which is the distinction that actually matters.

Which games on this list have zero missable achievements?
Hades, Vampire Survivors, Dead Cells, Celeste, Risk of Rain 2, Ori and the Will of the Wisps, Neon White, and A Short Hike all have zero missable achievements. Start with these if you want a stress-free roadmap where no wrong decision blocks the finish line.

Is Baldur’s Gate 3 worth 100%ing, or is it just time padding?
The 54 achievements require you to play BG3 the way it was designed — multiple times, with genuinely different choices that produce incompatible outcomes. The 437–800 hours is real playtime across different origin characters and story branches, not repetition of the same content. If that sounds like more game rather than more grind, BG3’s list is among the best-designed on any platform. If you want a single cohesive run, stop after one.

What’s the longest game to 100% on this list?
Terraria at 200+ hours including the 200 Angler quests is the longest focused achievement run. BG3 is competitive at 437–800 hours, but a significant portion is fresh playthrough content rather than repeating the same sequences. If you’re counting total engaged hours, BG3 wins. If you’re counting pure achievement-hunting hours (as opposed to playing new story content), Terraria is the longer grind.

What should a completionist play after finishing Hollow Knight?
Hades or Celeste, depending on what you found satisfying. If you liked Hollow Knight’s boss mastery arc, go to Celeste for the skill-expression progression through B-sides and C-sides. If you preferred the lore drip and discovering new content through replays, Hades delivers the same loop with more narrative density and no missables to stress over.
