The GTA 4 equivalent of the Statue of Liberty is called the Statue of Happiness... Broker is the GTA IV equivalent of Brooklyn, Manhattan is now called Algonquin, Queens is now Dukes, the Bronx is Bohan, and New Jersey is Alderney. The map is smaller than San Andreas, but considerably more detailed. No countryside or desert, we are led to believe.
A Smaller map than SA? What?
