-The protagonist's name is Niko Bellic - an Eastern European immigrant who has come to Liberty City to live the "American Dream."
-The GTA 4 equivalent of the Statue of Liberty is called the Statue of Happiness, and DUMBO (Down Under the Manhattan Bridge Overpass) is known as BOABO (Beneath the Offramp of the Algonquin Bridge Overpass).
-In Grand Theft Auto IV, Rockstar have recreated 4 of the 5 boroughs in New York, as well as part of New Jersey. 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.
-Pedestrians are far more realistic in GTAIV than in previous GTA games - they sit on benches, smoke cigarettes, read books and generally act like any real pedestrian would in the middle of a street.
-The screenshots in the preview are not representative of the final quality of the graphics, Rockstar insist. The game will only look better as the release draws closer..
