Doom 3 is an awsome game. Great graphics and audio. If you have 6.1 surround it makes it even better. I bought the collectors edition with the older Doom games on it because I loved Doom 2 when it came out and playing it on XBox was better than the computer. For the controls anyway.
No, I haven't played the expansion pack, but I'll probably be getting it soon because it is only $20. New levels, new monsters, and they brought back the double-barreled shotgun. I can't wait to play it.
