After playing a number of online games over the past 3 years, little has changed.  Sure, the variance of games certainly has changed but the best game available is still Quake2. Quake2 has by far been the most popular multiplayer FPS game since its release.  Games like UT, Half Life and Quake3 just haven't cut it.  Unreal Tournament and Half Life don't come close in the many features that Quake2 has to offer.  Versatility in gameplay and choices for the gamer on the internet are Quake2's biggest selling points.
