			I think players shouldn't play as zombies. they should play as groups of 5 or 10 zombies with an rts like interface.
as for my ideas several new concepts here have mad them defunct. the best plan is to openly discuss it.
I think I have a town hall blueprint somewhere...
		
		
	 
I'd still say AI zombies would be better.  But that's my opinion for (coincidentally) a game I've been working on since 2001.  Man, one of these days I should really get started on trying to get it more organized =P.
Anyway, an open world would be way cooler than a single building, too.  However, I still think a community created MMO would be pretty hard to pull off successfully.
I like the idea of AI zombies more as well.  Can you give some details on your game?
