For me it’s probably Jazzpunk, but I liked Disco Elysium too. I’ve been looking for something to scratch that “Jazzpunk surrealist comedy itch” for a while and not many games have come even close.
Have you played Katamari Damacy? I feel like it was a pretty obvious influence on Donut County.
PS - Donut County is on Gamepass for anyone who has it.
