I"m assuming to have a Gamertag I first need xbox live... and I'm a little short on funds at the moment. Altho I did manage to pick up 2 games that I've always wanted, DOA4 (Which I'm a little disappointed in, it seems I can't double tap my controller like I could in DOA3 on my origional xbox) and Burnout Revenge. I had that one on my PS2, but after playing it on the 360 it became rather difficult to play in SD, now I get to play in 1080P! WOOT!
COD World at War is always a good one
I would except I can't play FPS games on a console. I must have a keyboard and mouse to play those.
