Well you could buy Saints Row 2 and then use the cd-key on steam. I had already gotten Civ IV when I bought the giant 2k games pack when it went on sale a while ago.
I've been having fun with the multiplayer, except for the fact that nobody seems to talk in the game (which is surprising on the 360).
If anyone is up for some destruction tonight, send me a friend request and we can set up a party.
