For me it's Super Mario 64 and Super Mario Odyssey, for similar reasons- just to recapture that feeling of "oh my God I have this big world I can freely explore and it's blowing my mind"
silent hill 2- not knowing the story and playing completely blind would be amazing to feel again as the story happens or undertale for much the same reason
Kingdom Hearts 3 because literally nothing is gonna measure up to finally getting it after over a decade, and I will never ugly cry as hard as I did in certain bits
and honestly any game where the core of the gameplay is solving puzzles that require having or researching real-world knowledge while going โwhat the fuckโ at the story unraveling - The Return of the Obra Dinn, Black Watchmen, etc
Because I play a lot of old things where Everyone Knows what happens and that is why I got interested in them! But it would be fun to go into like, Fire Emblem 4 without knowing what happens in chapter 5
IA with you there, Eileen- like, when I watched a let's play of Portal I'd already had so much of it spoiled for me due to the memes, I feel like I would have liked it a lot more if it was fresh
Aside from Portal (especially 2) and Okami, maybe like... Pokemon Red/Blue? As a kid, it was so full of wonder, not knowing what sort of fantastical creature was waiting for me just in the grass ahead
yeah I feel lucky that I went into Bioshock blind to the story despite getting into it like 10 years after it came out. Wish I could experience THAT again
or undertale for much the same reason
