Thats pretty impressive, but as you can see, they only used real life photo ground pictures, and add bland boxes over them, while it looks good from above, it wont look so good from below.
On the other hand, I'm much more impressed by GTA IV, but I'm very dissapointed on Rockstar's decission to flat out copy New York City. Unlike GTA 3 where it was simular to NYC but had their own towers.
I was inspired by patrick,so I made this. This is probabaly my favorite shot of the city ive ever done.just don't mind the water in the upper corner,theres just no grid there.
