what you need is what our house has. a network set up including 3 xboxs with a large tv and 4 controllers each. makes for some hardcore halo2-ing on weekends.
thats 12 people max (more if friends bring round extra xboxs and tvs, which they do!), and we normally have 1 team per room so we can talk tactics (as if we ever bother with those) and shout obscenities through the house when someone kills us
