this would also be where i would stop playing it. it would take the skill out of war.. not gonna happen captain
Wouldn't necessarily be an RPG (i.e. WOW), but a Massively Multiplayer Online Shooter. I expect that this would lead to massive battlegrounds with RPG based player interaction. I think that this would be quite interesting.
Most definately would have to be an FPS...but between rounds...you could incorporate some kind of MMO aspect. Like use experience to purchase guns...perks...etc. Would give you an environment to communicate with clan members... and stage strategies and goals. There could be built in leagues...territories to control...and prizes to be won... I am going into googoo land now I know... but it might be cool.
