Mostly the same here with a few exceptions.
Nethack is a game I would love to finish, but I always end up killing my self in weird/wacky/hilarious ways. I just can't bring myself to play it "safely"
I would love to finish Tombraider: Anniversary some day, just to convince myself that this pile of goo has some hidden, redeeming features somewhere.
Zork III, just because.
Trespasser, because I actually liked running around in that world, despite the awkward controls.
Probably more lying around (not including stuff that I have no intention whatsoever of touching again).
