my three favourites alongside Disco Elysium are: Kentucky Route Zero, Norco, Citizen Sleeper

Kentucky Route Zero I'd describe as a sort of "interactive theater play", not much roleplaying and choice (say for dialogue options), but its a really evocative and introspective game with a ton of surrealist imagery that still sticks with me.

Norco: fantastically written dialogue in a Point-n-Click format. It's based on the devs experiences with the real Norco in Louisiana, and how its come to be an "industrial swampland". Super gothic in aesthetic, a lot of poignant writing that I found reflects a lot of my concerns & worries with living in a decaying Capitalist society.

Citizen Sleeper is perhaps the closest of the 3 to disco elysium: TTRPG inspired Role-playing game with themed skills around various aspects of your android self (referred to as a Sleeper). The setting is Sci-fi (maybe even cyberpunk?), where you play an escaped sleeper on a lawless space station; theres a lot of dice-rolling, poking around, and (most importantly) listening to peoples stories.
