I've just broken my left collarbone and for the next couple weeks have left arm in a sling. Thinking about games that are played just with the right hand?
I've already got Slay the Princess which I've been meaning to get around to for a while and Disco Elysium which I never got far through, but taking any suggestions at this point, always keen to try fresh genres and formats.
Maybe some classic, more phantastical CRPGs with turn-based combat are more your juice than Disco Elysium: Baldur's Gate III, Pillars of Eternity II, Fallout. Planescape Torment, Tyranny, Pathfinder, Pillars I and the rest of the Baldur's Gate series rely on real-time combat with pause which might get tedious when only using the mouse.
