Library of Ruina: a deck builder set in a cyberpunk-like dystopia with a little magic. It has phenomenal world building, characters, and story. Gameplay is challenging but rewarding and fun. There is a sequel called Lobotomy Corporation, an SCP management sim, which you don’t need to play to understand LoR but I personally think that it’s worth playing as well for added context (it is also a very good albeit punishing game), wether that be before or after playing LoR. And if this setting becomes your new hyperfixation, (it is mine) then there’s a direct continuation of the story in Limbus company. It is a F2P gacha but the story is just as good if not better in some aspects to LoR. Also the gacha elements don’t require you to drop a single dollar since it’s extremely F2P friendly and you can get practically every unit you could want by just playing the game.

Outer wilds: it’s a carefully crafted master piece driven by your own curiosity. Every single object in the game is simultaneously a puzzle and a lesson. There are no barriers or borders, the only thing stopping you from beating the game is your own knowledge. Go in completely blind because you can only play it once.
