Yes, I am a big fan of ID. I was one of the geeks who played all of the Wolfenstein levels you could find, I played the various Commander Keen releases too damnit. I was one of the idiots waiting for ID to release the original Doom, which they couldn't because the site they were supposed to release it on was clogged with slobbering geeks awaiting the download. I played a huge number of add on levels of Doom. I played it over a modem, I played it in a group lan.
And Quake was even worse for me. So many LAN parties which included a horde of Duke Nukem. I was in one of the top Australian guilds.
Quake 2 was fun ... in single player mode. Quake 3 was good intense fun for quite a while through the demo but never really made a hit with me for some reason. I guess that was when Everquest came out. So I wandered in my ID following. Return to Castle Wolfenstein was ok except when some of the bosses were just a little too hard I just went on to more fruitful ventures in life. Like anything. Vietcong provided a whole new feel for a while. Unreal Tournament with co-operative against bots was VERY entertaining. I have a friend who is in love with Serious Sam, and that was a real blast to play through on co-operative. I have played the Unreal Tournament 2004 demo and love the vehicles and taking over power towers. But it gets to the point where you know which side is going to win and the rest of the game is spent in futile resistance or bothersome stamping out of the opposition.
I knew there were a heap of other great software out there but you really have to limit yourself to something that will entertain you. LAN days where you spend half the time changing software is not really too much fun.
Doom 3 has been on the cards for a long long long time now. There was a "release" of a beta that showed a pretty neat environment - but wasn't overly interesting. The hype has been steadily building since then. The current reviews of the game are as good as you will ever get. Doom 3 was released last week and I have been playing it on and off whenever I get the chance. To make it simple for you, I approve and agree with what the reviews say: this is an awesome and defining game for it's genre. This game will scare you.
I love the tribute to the Doom monsters and setting. Some rooms I can pick as being right out of the original Doom. So should anyone who has had the Doom dreams - you know what they are if you have had them. And if you have had them then you have played Doom seriously too much.
