Some good games for the 360

Gears of War ( a must have)
Quake 4 ( An awesome fps with a decent story line)
Guitar Hero 2 (Online mode allows for downloading songs)
Tiger Woods ( Good game, online capabilities)
Madden

Then games to have just because

Doom 3 (Scary Shit- play drunk and watch yourself pee your pants)
Halo 1 and 2 (the 3rd is out on Sept 25th)
PGR (who doesnt like car games)

I love the system, but some of the games are not for me. Im looking foward to the game releases at the end of the year (Decemeber)
