I'd second Forza 2, but if that's not your bag, one of the only games you don't have that will give you a nice long length of gameplay, is "Marvel: Ultimate Alliance" the campaign is well over 20 hours if you take the time to enjoy it, and with either the new gold edition or the DLC on live, you have like 25 playable characters, and then there is another 7 or 8 to unlock and a ton of other unlockable stuff, it's a good game to get into for the summer and have last you more the typical shooter. Plus you can level up all your characters and beat the gameand then start the game again with them at that level.

You could save it for Bioshock or Mass Effect, or Assassin'sCreed, but those games are all out after summer is eitheralmost over, or until the year is almost over, so if you want something for summer your choices are short.

Overlord and the The Darkness are coming soon and good begood options too.
