I'm pretty sure Counter-Strike 1.6 might run but Source wouldn't be playable. Also it's pretty hardcore.
Minecraft is pretty heavy despite how it looks like.
I think of a game that I could play with a friend, casually. I thought it would be easy, but there really aren't many nice lo-fi co-op games.
