* The protagonist's name is Niko Bellic - an Eastern European immigrant who has come to Liberty City to live the "American Dream." The game is set in Liberty City in 2007, but it is bigger than the Liberty City we saw in GTA III.
* 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.
* Rockstar is giving its players more freedom, more choice, and more sense of control over their destiny — the structure of GTA4's storyline is quite different to it's predecessors as it can be told in a number of different ways. You can talk to people in person, by cell phones, and there are a bunch of other ways of giving the player information... In previous GTA games you were like a slave because you had to constantly take orders from people when doing missions. There is still an element of that in Grand Theft Auto 4, but you can also choose how you want to spend your time...
* There are no planes in GTA IV because there is only one city, and Rockstar want the game to seem realistic. That means there will be no rollerblades, no unicycles, probably no jetpacks and indeed no planes. Rockstar are giving choice and variety which feels right for the character. However there will be motorbikes.
* After an initial load sequence, the game will never load again. Not even during exterior-interior transitions (and vice versa).
* Both versions of the game (Xbox 360 and PlayStation 3) will likely be identical, but the Xbox 360 version will have exclusive downloadable episodic [sizeable] content. Rockstar have now spent over 3 years developing the game, and Dan Houser compares the leap from GTA III to GTA IV, to the leap from GTA to GTA III.
* GTA IV will have multiplayer, but it's not going to be a massively multiplayer online game, says Dan Houser. They are trying to make something that is interesting, fun, progressive and which goes along nicely with the single-player game.
I want more silly vehicles like an electric wheel chair or shopping cart
