Yes, Doom was a very good port. Aliens vs Predator was excellent. As far as I'm concerned it was their greatest game. Man, back in the day it scared the poo out of me - LOL. The funny thing was that what made it so scary was likely partially a hardware shortcoming. It didn't have music playing during your exploring the ship you were on so as you explored it was complete silence except for the occasional noises that creatures made and it was then that the hair on your neck would rise!! Oh man I could only play that for short periods with the lights on! I scare easily anyway though - lol!
Yeah, just always enjoy what you got. It's all about the fun!
