I know another good reason... could it be because... QUAKE II IS THE GREATEST COMPUTER GAME AND FPS EVER! StarCraft and Quake II are all I play on my Mac. Sure, I got all my other beloved iD and Blizzard games (Warcraft II, Doom, Wolfenstein, Diablo, etc.) but Quake II is only the greatest computer game EVER! StarCraft being a very close second.
God damn I loved Quake 2. I can still remember the CTF maps in my head! I wish 3 team CTF had caught on more. Most of the few servers that did run it never had enough people for good teams. Bless this game.
Doom/DoomII kicked much ass too. Anyone here use The Simpsons mod for D2? Annoying, but cool at the same time. And that USMC mod that soldiers used for training was pretty cool too. Hard as hell though
