I had both but i sold my xbox because i could care less about the exclusives on it, and i really never bothered to use it.
Come to think of it, i should sell my ps3 too, but then i wouldn’t be able to watch James Cameron movies on blu-ray (not avatar). My ps3 was basically only used for MGS4 for me, and my (now gone) xbox was used to play halo 2 & 3 because i never got the PC version of halo 2, and obviously halo 3 is only on xbox. I beat halo 2, and got bored of halo 3 after a little while of playing. I obviously didn’t care for them that much, or i would still have my xbox now.
