This is just a list of some of my favorite games, so it probably won't be everything -The Binding of Isaac - I have about 600 hours on this game, it is incredibly fun and has a lot of replayability.
-Hollow Knight - opened me up to Metroidvanias, as well as having an incredible story and super fun bosses.
-Celeste - my favorite platformer game ever, has super fluid and responsive movement, and a great story, as well as a lot of challenging gameplay.
-Enter The Gungeon - one of the very few games where I have no idea what's happening, yet is still enjoyable to play.
-Terraria - I hate the Angler, 10/10 grinding
-Bloons TD 6 - very good when playing for fun, very stressful when going for difficulty badges
-Geometry Dash - FIRE IN THE HOLE
I'll add more as I think of them
