But this thread should be locked because the two games are nothing alike. If you were to say COD4 or Halo then it would make sense. But GTA and Halo reallycan't be compared.
I've stopped playing Halo, not because I don't like it, but it's just not as fun to me as it used to be. All I been playing lately is Bully:Scholarship Edition and NBA 2k8.
With that said... Acheivements + Downloadable content + multiplayer + already owning a Xbox 360= GTA IV on Xbox 360 FTW. 17 days...
