anomalous cohort writes "I am a casual gamer. Go or Chess are my games of choice when I am up for a serious intellectual gaming challenge. Otherwise, I just want to blow off some steam in a free, arena-style FPS such as Alien Arena, Nexuiz, Sauerbraten, or Tremulous at the end of a long day. Either way, it is very rare for my gaming experience to exceed 30 minutes. The problem is that attendance for these games has dropped off over the years. Finding a game with about two humans and two robots is perfect for me and very rare these days. My question is this: What is currently the most popular free, arena-style FPS for the casual gamer that you know of?" That reminds me, how is the Quake Live beta coming along?
