One of the things we discussed, either here or the 'other' board, was the fact that Doom wasn't just a run through guns blazing game but that music just made you want to hack and bust a hole in every NPC you found. I don't think I have ever played a game where I have actively gone around looking for fuel to use the chainsaw more than the actual assault weaponry at my disposal.
The only gripe I had with it was that it was too short and lacked any real story plus I think it really didn't do itself any justice in terms of difficulty until you pushed the level up much higher and then the hording became much more challenging to engage. After reading your comments I am actually tempted to go back and give it a run through again. I always envisioned Prey to kind of have a similar mechanic but that game is nowhere close to the amount of fun Doom gave me.
