myself and my rc ball m8s would definately be interested..
its very rare you get the chance to play in an urban enviroment..
As you said, rules for a game like this would have to be relatively simple, perhaps something simmilar to Unreals Domination style of play with 2 equally divided teams and perhaps 3 domination points..
(Real Medal of Honor stylee gameplay..)
i think its a fantastic idea!!
