sounds like you like first person shooters, so if that's the type of game you're looking for I echo the people who said Timesplitters 2. If you want to wait or want to know about future FPS multiplayer games for the Cube, there will be some of those released between now and mid January including Timesplitters 3 and Goldeneye Rogue Agent, there could be more I forgot but that also depends on whether the companies will decide to release them on GC too. Ofcourse now that I think of it you have an Xbox so you'd be better off getting those on XB, but you already want Halo 2. Nevermind then if you want good FPS multiplayer now, Timesplitters 2 is the best and it's only $15 used and $15-20 new.
