After Brotato addiction I found this gem of a game, right before the sequel announcement it seems. It's such a perfect game for the Deck at least for me - you have time to think, the controls just work and you can just put the game down and continue your run later.
Do yourself a favor and try it out even though your first runs will probably be a disaster. The core game mechanic is so tight and well done it's a pleasure to play loop after loop. 50 hours later I still want to do 'one more run'.
Hades and disco Elysium are both incredible experiences. Hades when you're feeling reflexive on point and rogue lite with a hell of a story and development, disco Elysium when you want a long story driven narrative branching and repeatable.
If you want another game, with equally great story, on the entirely opposite end of replayability and gameplay (and equally highly regarded by most critics) add return of the obra dinn to your list, it also works great on the deck!
