One handed games

Haha, MHF 5. Got the same one after I tried punching the bottom out of frustration over DMC. Well, for games, there are some suggestions already like adventure games or turn-based games. Out of my library the ones i consider playable with one hand are: Cherry Tree High Comedy Club, Cthulhu Saves the World, Monster Loves You!, RUSH, Element4l, Toki Tori, Underrail.

hearthstone. you dont have to use much.

If you never played it ... Syberia 1 & 2

This might be a good time to buy a mouse with a bunch of programmable buttons. :)

That would open up a lot of arpgs for you. Until then...

Sanctum SD and Sandbox Universe come to mind.

Wow, thanks you guys, Civ is a pretty good option I've been meaning to get into the 'new' DLC.

Thanks Eldrands, but the Doctor told me my pinky will most probably never again function like it did before.

Neo Scavenger, Zafehouse: Diaries

Xcom EU can be played one handed, and it's great fun!

Sorry to hear about the fracture, looks painful. :-/
