If you're able to use your left-hand with a mouse that supports some macros, Diablo 3 is very mouse-playable. Primary and secondary attacks are bound to left- and right-click, skills are 1-4, occasional potion clicking is Q, town portal is T and... that's it, really.
Good bit of fun too, has some endgame gear grind to start perfecting things but there's a fun story if you've never played it, and I'd be down to help you in-game if you have questions and such.
If you pick it up let me know, I'll PM you my B.Net name and you can add me for some fun (depending on timezones

). For a trial, you can try (I'm pretty sure) the Starter Edition and Guest Pass (you'll need a Blizzard account, as with all their games, to play) -
