LAN Info and Discussion

I've been contemplating the idea of having a tournament between a few teams at the LAN.
A points system and a winning team at the end will add a competitive atmosphere (that I personally love).
It will have to be round robin since there are only three teams.

Also I think that this will reduce the amount of lulls in action at the LAN, especially as it gets later into morning.

What does everyone think of this idea?

How do you want the teams organised?
Pre-determined or form them at the LAN?
What games do you want to compete in?

Or do you not like this idea and prefer to just do what we usually do and just casually play the games at our leisure?

I personally would prefer to have teams (don't really care how there organised) that we play with throughout the night for the designated games. But for everything else we just wing it and do whatever. So its a mix of competitiveness and simply chilling out.
