OK to get one thing straight,the xbox verison of doom 3 is not a port of the pc one.To get pull into it on detail,its being done by other ppl then the pc one.Another thing that was said at either gamespy.com or gamespot.com is that its a totally different kinda of game so thereful you cant say either one is better then the other.So I dunno about story or whatever,but its supposed to be the same story but a totally different kind of game other to the pc one if you can understand that.I for one have took my doom 3 back cause of issues lately with it and got my money back.
