I agree with the guy that said Outer Wilds, even though I can't finish it because of my thalassophobia.
Personally, the two games that had a really profound effect on me are Disco Elysium and Hi-Fi Rush.
Disco is an incredible political game that really is damn powerful. It's definitely not for people who just want action.
Hi-Fi Rush is a rhythm action game so I wouldn't recommend it to people who hate rhythm games or people who hate action. But it's so fun, so charming and really uplifting.
Disco is terrible, lazy writing. It's just endless word vomit.
I like literature, smart word play. but this ain't that. This is just throwing everything including piss, vomit, semen and feces on the wall and see what sticks. And in a lot of early game scenes it's this quite literally.
Anyway, what I'm trying to say is that Disco is not for everyone. You love it or it makes you nauseous. There is nothing in between. And you only know which one is you when you try it.
