If you haven't wasted your money on the Xbox version yet, you might try this one out for size

User Rating: 5.5 | DOOM 3 XBOX
Alright everyone, does anybody remember what made Doom and Doom 2 great? Well I do. It was the fact that you were fighting about 200 guys at once, and they died really quickly, but you had to keep running like a madman to stay away from them. So the action was incredible! This game, it everything that it shouldn't be. It shouldn't be called Doom 3, it should be called, A game similiar to Doom only in one facet, you fight demons. The basic gameplay of Doom 3 is taking on huge enemies one at a time and having to unload clip after clip into them to kill them. It basically becomes an exercise in holding the trigger down while pointing at their heads. Not really worth it if you ask me.

So about the point distribution.

The Gameplay is not worthy of the name Doom. Its still scary, but its not intense like Doom 2.

The graphics in this game are top notch. If you are like me and cannot afford a dream pc then the Xbox version is the one to get. If you are going to get one.

The sound is alright, doesn't really take advantage of the Xbox's power.

If you have Xbox live then the game has quite a lot of replay. If you don't its a simple once through 10 hour shot.

Tilt, well I hated the PC version of this game, because it requires way too much for being such a crappy game. But renting the Xbox version wasn't a bad idea. Its worth 7 bucks.
