At initial release, the CE and the regular version of Doom 3 for xbox had a $10.00 difference. But I got it anyways because of its cool metal case. I really enjoyed Doom 3 for xbox when I bought it. I mean I actually had the chance to play Doom 3 without owning a computer that can run it. And I agree that there are some changes in the game, (portions of levels cut, "dumbed down" graphics, and missing items.) but they really don't make the game that bad. Unless you're a PC Fanboy that has to complain about the graphics, I dont see why anyone has to complain about this game.
