They'd have to introduce some kinda reward system for teamwork in a game like that, cos like you said you'd need to be pretty 1337 to do it properly!
I cant wait till some of the next-gen games. The extra power means you'll be able to have it all. Im looking forward to games with that intense graphical immersion factor, with sprawling landscapes where you can see detail for miles and hear the leaves rustling on trees in the distance, or maybe have a city landscape with shiny skyscrapers all lit up perfectly by a low, orange setting sun (and HDR!). Its gonna be immense!
