That is a great idea, get people out of their homes to play a real game.
Reminds me of one of the funniest South Park episodes called 'make love not warcraft', check out about 1.30 in, the guys are playing WoW for days on end non stop, slothing in front of the computers, when cartman has some special power and cant leave to take a shit, "thats a big boy isn't he"  GOLD!
