As I posted on SA:
I don't see the problem with not doing a state this time. Since they're working with new tech, I'd like to see what they can do with one individual city first. One city with a downtown, suburbia, rural area;etc. would be just fine if you ask me. I love San Andreas to death, but in this case, I'd prefer seeing Rockstar a more concentrated area this time just to show off what they can do.
