HARD MODE: Don't say Undertale
I think mine is probably DOOM 2016. I don't know that I've ever had more raw, uncut, can't-believe-how-much-I'm-enjoying-myself FUN than my first time going through that game. I legit was hooting and cackling like a madman while scrambling around blasting demons and dodging fireballs and getting sick glory kills. My first playthrough was roughly 20 hours of some of the purest joy I've ever experienced in my life and I'd give ANYTHING to experience that again.
Honorable Mention: Heaven's Vault. GOD, that game is cool.
Had difficulty choosin' just one. Though... I'd say Kirby's Dream Land 3.
Everything about Kirby fills me with joy. Dream Land 3's art style oozes whimsical charm that I wish I could experience with fresh eyes. What I'd give to re-experience the soundtrack's mad range of unnerving (yet calming) to delightful tunes. The simple fun of mixin' n' matchin' copy abilities with Kirby's friends. An adorable game that I keep in my rotation of games I play.
I considered Tales of Vesperia, but—honestly—while mostly everything is decent or great about the game... the fact you need to follow esoteric paths to unlock the fun stuff isn't, well, fun lol
