I wouldn't even consider most of those categories worth having a competition for. Fighting, casual, sports, MMORPG, etc are not what 'real gamers' play. I guess to each their own and if people enjoy those games, power to them. I just can't see those being particularly entertaining to watch or very competitive. I'm interested in the FPS and RTS genres. I wish they had COD4 as a choice, its still my favorite FPS. Nice to see the new Quake Live making an appearance there. As for RTS, I voted for SC2.
@zerapio,
There is a link to the survey. I filled it out.
