A bunch. Mostly console games that I repurchase for PC when they become ridiculously cheap. Some HD re-releases on PS3. I've also sold games that I didn't think I would play anymore, but ended up having the urge to play them again. Which is why I never sell my games now, no matter how sure I am that I'll never play them.
