Games that Make 100% Completion Actually Worth It

Most games treat 100% completion as its own reward. You did the thing, here's a number, goodbye. The worst offenders (looking at you, Yoshi's New Island) give you nothing, or maybe just an achievement that pops on your screen for three seconds and then disappears forever. The slightly better ones give you a cosmetic nobody asked for. And then there are games on this list which understand that players willing to go the distance deserve something more elaborate in return.

What separates a good completion reward from a bad one is whether it feels like the game was genuinely saving something for you, rather than tacking on a bonus as an afterthought. It might be a secret boss that only the most dedicated players ever get to fight. It might be an ending that finally resolves something the main story left open. It might be a message from the developers thanking you personally, which sounds small but always warms my heart.

Whatever form it takes, the best completion rewards feel like the game shaking your hand and meaning it. These ten get it right.

10 Spyro: Year of the Dragon

A Whole Second Boss Fight You Had to Earn

Most collectathons reward 100% with a cutscene or an achievement. Spyro: Year of the Dragon gives you the Super Bonus Round – a full extra stage with its own escalating sequence of challenges. You fight thieves for gems, then take Hunter's submarine to destroy Rhynoc subs, then race the Sasquatch Six on hoverboards in what is genuinely one of the hardest optional challenges in the game. Win that, and you get a Superflame power-up to take down flying saucers. Then, and only then, the final door opens for a rematch with the Sorceress.

The Sorceress fight is hard. She speeds up as the battle progresses, her fireballs are difficult to dodge, and flying into the acid below kills you instantly. The 150th egg, Yin and Yang, drops when you beat her. It's a complete bonus level hidden behind full completion, and it's exactly the kind of thing that makes collecting everything build towards one last love letter to everything you’ve seen in the game.

You Catch God at the End

Completing the Pokédex in Pokémon Legends: Arceus – which means reaching Level 10 on every entry, not perfect research, but still a significant investment – rewards you with the Shiny Charm, which dramatically improves your odds of finding shinies. During Mass Outbreaks with the Charm equipped, the ratio jumps to roughly 1 in 140. That alone would be enough for a lot of players.

The real reward, though, is Arceus himself. The literal god of the Pokémon universe, the namesake of the game, is only catchable after completing the Pokédex. The game tells you at the start that you'll meet him again after discovering every Pokémon, and it keeps that promise. Battling and catching Arceus is the best Pokédex reward any game in the series has ever offered. It's not a charm or a certificate. It's the actual end of the story.

8 Super Mario Galaxy

A Message from the Developers

Collecting all 120 Power Stars and defeating Bowser a second time unlocks Super Luigi Galaxy – a full replay of the game as Luigi, with his own distinct movement and physics. That alone is a pretty substantial reward and a very exciting take on the usual New Game+ slog. Collecting all 120 stars as Luigi and beating Bowser again unlocks the Grand Finale Galaxy, a short final stage with one last Power Star for each mode.

The part that really got me was what happens after you’ve done that, though: talk to Mailtoad and you receive a message sent to the Wii Message Board: a congratulatory note from the Super Mario Galaxy team, thanking you for playing to the very end. A galaxy-sized thanks, signed by the staff. In the Switch port, it's read out in-game. It's a small gesture, but it's genuinely warm in a way that a trophy or achievement never quite manages to be.

7 The Legend of Zelda: Majora's Mask

The Most Powerful Weapon in the Game, for Bosses Only

Collecting all 20 non-transformation masks and trading them to the Moon Children inside the Moon earns you the Fierce Deity's Mask – Link's most powerful form, wielding a double-helixed sword that fires magic beams and tears through bosses in seconds. By default, you can only use it in boss rooms, which is exactly where you need it most.

The sting in the tail is that using the Fierce Deity Mask prevents you from seeing certain ending scenes – nine of them, tied to sidequests that each have their own associated mask. The game builds in a genuine tension between power and closure, and it's the kind of design choice that respects the player enough to make the reward meaningful rather than unconditional. In the 3DS remake, you can use it in fishing ponds as well, if that's important to you.

6 Stardew Valley

A Hat that Makes You Look Like the Developer

Stardew Valley's Perfection system rewards full completion with a layered set of genuinely lovely unlocks. The Summit opens – a path blocked by a boulder that only moves overnight once you've hit 100% – leading to a cutscene with your spouse or favourite NPC. The Statue of True Perfection generates one Prismatic Shard per day, which is extremely useful. Golden Chickens become available, producing Golden Eggs. Grandpa's Shrine gets a Stardrop carving. A flock of Ginger Island parrots fly over your farm.

The one I love the most is the ??? Hat. Go to the top of the Volcano Caldera dungeon and find a monkey sitting in the lava. Interact with it. You receive a mask that makes your character look like the ConcernedApe logo from the start of the game. It's completely silly and completely perfect, and it's the kind of thank-you note that only an indie developer with a personal relationship to their own game would think to leave.

5 Kingdom Hearts Final Mix

A Glimpse at What Was Coming

Kingdom Hearts' secret ending, "Another Side, Another Story," was already something special in the original game. The Final Mix version expanded it into "Another Side, Another Story [deep dive]" – a longer, cryptic sequence that teased the wider Kingdom Hearts mythology years before anyone knew what it meant.

On Standard difficulty, unlocking it requires completing the Hades Cup, finding all 99 Puppies, sealing every Keyhole, completing Jiminy's Journal, and finishing the game. It's a genuine checklist of commitment. What you get in return is a secret ending that the community spent years dissecting, theorizing about, and arguing over – a reward that wasn't just content but a mystery.

4 Donkey Kong Country: Tropical Freeze

Hard Mode with No Checkpoints

Reaching 100% in Tropical Freeze – all K-O-N-G letters, all stages, all bosses – unlocks Hard Mode. In Hard Mode, you start every level with one heart, there are no checkpoints, and the shop is unavailable. It is brutal in a way that the main game occasionally isn't. You can push further to 200% by completing Hard Mode and collecting all blue K-O-N-G letters, but that earns only bragging rights and a completion percentage.

What I like about this is that it doesn't give you a cosmetic or a gallery. It gives you a substantially harder version of a game you already love, gated behind having demonstrated that you can handle it. That's the correct design choice for this kind of game.

3 Okami

Infinite Everything, One Run Later

Collecting all 100 Stray Beads in Okami earns you the String of Beads – an accessory that grants unlimited ink, infinite solar energy, invincibility, and a tenfold attack multiplier. The catch: the 100th bead is rewarded for defeating the final boss, meaning the String of Beads can only be fully used in New Game Plus.

It is technically a reward you have to wait an entire playthrough to use properly, which sounds frustrating until you realise that it turns your NG+ run into an extraordinarily satisfying victory lap. You've earned the ability to be effectively invincible in a game you already love. The timing makes it feel more earned, not less.

2 Final Fantasy X-2

The Ending that Fixes Everything

Final Fantasy X-2 was not designed for 100% completion in a single playthrough, and most players won't hit it on their first run. The percentage carries across playthroughs, and the reward for getting there – combined with saying the right things in the sequence after the final boss – is the perfect ending. The one that resolves the heartbreak of Final Fantasy X in the most satisfying way possible.

I won't say more than that for anyone who hasn't seen it. What I will say is that if you finished Final Fantasy X feeling devastated and never went back to X-2, this is the reason to go back. The perfect ending exists, it's earned through genuine effort, and it's worth everything it costs to get there.

1 Hades

The True Ending Takes Eight Attempts at the Impossible

Escaping the Underworld in Hades for the first time is an achievement in itself. It isn't the ending. The true ending requires Zagreus to defeat Hades and reach the surface eight times, then build his relationships with every primary Olympian to their peak – each of whom only appears by chance, meaning the process requires patience and persistence across an enormous number of runs.

What's waiting at the end of all of that is genuinely moving. Reunions. Reconciliations. Family conflicts resolved. Hades himself, unburdened, behaving with warmth toward Zagreus for what might feel like the first time. The game earns every beat of it because you earned the right to see it. Supergiant built a true ending that is only available to players who committed fully, and they made sure it was worth committing to.
