So for my vote or preference, I say stick with FPS. My ranking as far as tournament potential and interest:
1. BF 2142 / COD4 - highly tactical and very much team based
2. UT2004 - more room for lone wolf players, not sure on how many tournaments are ongoing, Onslaught is megafun
3. Q3A - very rough for inexperienced players, still a ton of fun but individual skill level requirement is HIGH, CTF and Clan Arena somewhat team based
I would love for anyone who chimes in to place their votes/preferences in order (any genre) and maybe give a little info about why you think the clan should concentrate on that particular game.
