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.
While we're talking about tower defence, I really recommend the Gemcraft series! IMO probably the best tower defence games out there. Chasing Shadows and Frostborn Wrath are both on Steam, and I highly recommend them.
