Funny you should mention this... I play overseas and big games of 100+ people are going on all the time. But the thing that kills me is these guys talk, and talk, and talk.... then we play.... sort of.
Usually the head guy yaps his arse off to everyone about every possible detail or outcome, the list of rules as long as my leg for about an hour, THEN gives the individual teams their briefs....!!! And the thing is, its not all that complicated or indepth!
But hey, beggars cant be choosers so I keep my yap shut. ; )
