If you are really interested in team based tourneys, you should check out Appalachian State University. The last one they did in the fall was like that. However, as GXTI stated in his reply we, at WCU, are here to support the University and its students. The founders of the WCU Gaming club did not favor the layout of a team-based LAN, which is why we have never required nor allowed teams at our LANS.
We do charge a small nominal fee to attend-$5 which as LordKuros mentioned does pay for the bountiful food and drink in which you will be supplied.
As our LANS are BYOC, bring your own computer, many games will be played. We limit the actual tournaments to those inwhich there is sufficient interest. However, many games are played.
At our last LAN, we had a Nintendo Wii, X-Box 360, Guitar Hero, and DDR, as well as many PC games. We only had 4 tournaments out of those. One was on the X-box 360-Halo 2 and Gears of War, and the other 2 were PC-CS 1.6 and Q3. Unless I am mistaken.
We are growing in numbers with each LAN we do, however I believe that it will still take some time for us to reach 1000. Again we cater to our students first and foremost. The mission of the WCU gaming club is to bring more students to WCU. We are accomplishing this goal.
I thank you for your interest in our upcoming LAN, welcome you to attend, and encourage you to continue to play on our servers.
