I was an avid Doom player, then made the move on to Quake. I joined Clan NBK which became 311. We had a couple Id Software people for members (john cash and bear). I ended up getting to know some of them pretty well. I got to do some design and testing on Capture The Flag, which ended up becoming part of Q2.
In the end, it was pretty cool and a few elements on the first CTF map that I did ended up making it into the Quake 2 commercial product. I loved being able to go to best buy, point at the box on the shelf and go "i have stuff on there!". Quite amusing for an 18 year old.
Oh yeah, and Kornelia was much better than Killcreek
