I agree. I thought it would be cool if GTA 4 took place in a futuristic setting or city. Not anything like GTA2, but more reminiscent of the city in the movie The Fifth Element ( In know it was a shitty movie, but stick with me on this one) with hovering cars, super tall buildings, all of which would be accessible, and different tiers of walk ways and such. I think it would really be something new and revolutionary much the way GTA III was revolutionary when it first came out. The possibilities for interaction with the different people (perhaps some aliens, or perhaps not), new weapons, vehicles other than just cars and airplanes, and maybe just some totally new shit that they come up with for the game that would only make sense in a futuristic setting, would be endless.
