...who play Tremulous?
For me, the answer is probably none. I turned a few people onto it, and even had a friend put up a server for a few months on a nice dedicated 24/7 box, but I can't say I actually know anyone who plays Tremulous besides me. But then, I'm old, and my friends are too. Most of the people I know who are gamers are WWII fans or X-Boxers, playing Battlefield 1942 or Halo. I've got a MacBook, and Trem is what it runs, so w00t! Tremulous!
You?
