well i can look into other games, I havnt player shooter competitively sense medal of honor allied assault so i dont know what the more popular ones are (I just beat crysis a couple of weeks ago so it was the 1st one to pop in my head), right this second I can set up servers for crysis, mohaa + expansions, counterstrike source, battlefield 2, red orchastra, I cn also find a way to moderate racing games such as NFS world, most wanted, carbon, underground 2, just to name a few. And of course there always is starcraft and misc MMO tournies (PVP tourny in wow namely, or in eve too).
