I've played OG Dead Space 7 times, and I've played the remake 3 times.

But I have played the story mode in Super Monkey Ball 2 at least 50 times so I guess you can count that.

I'm talking games that have a start and end, and you can go back to the start when you're done.

angry birds

(yell0wsuit's chrome one)

Minecraft, polytopia, dragon city and onebit.

Super Mario Odyssey

fortnite
hundreds of times

as in Fortnite Save the World?

Battle royale 😔

Terraria, countless times I've started new playthroughs but I never finish them

Sonic mania

Either Batman Arkham Knight

Or the CoD: Cold War campaign

definitely the 3DS Kirby games

Portal 2 like 3-4 times

Minecraft, many hundreds of times totalling over 5000 hours
Satisfactory a lot of times totalling 2700 hours
Those are my two mains

probably mario 64, subconsciously

ULTRAKILL. Played it an unhealthy amount and I don't regret it.
