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