This is everything I wanted Torment: Tides of Numenera to be.
Disco Elysium is an RPG with no combat system. It has every other part of an RPG: levels, skills, equipment, and items. But instead of combat, all your skills are based around investigation and conversation; and you will need them, because you play as an insane, dysfunctional detective who nevertheless has to solve a very important murder.
The game is bizarre and wonderful, and a model for how nonviolent RPGs can work.
