It's been tradition for them to jump from liberty city to vice city and san andreas. Of course i havn't played the london version where it was in britian or some shit. I think what you might see in the next game is the ability to travel to multiple cities like you use to be able to do in gta 1 and 2. I think the only reason they split them up was b/c of memory and to make more money obviosily. One thing that i noticed off hand was that the guy lazlow was from the midwest and for some reason he talked alot on the radio in gtaiv about the midwest. I'm from chicago myself. I think if they made a game based off chicago that would be kick ass. Chicago is one of the most corrupt cities in the country. When 4 out of the last 8 governors of illinois have served time i think that sets the bar right there.
