or you can just dowload the game from the online store and not have to go buy a hard copyi think it sells there for like $9.99 US and im pretty sure they have upped the graphics (everything was always blurry in the xbox version)
I think you need to download a patch for it to work.
Well BruinX used to have the limited addition Halo 3 xbox 360 which alowed you to play the orgional 2 on it. But i hav e eard that you may need to live to play 1 and 2 on the new xbox 360.
