Grand Theft Auto IV

Grand Theft Auto IV (also known as GTA IV and GTA 4) is an upcoming sandbox-style action-adventure video game by Rockstar North. It will be the ninth title (and the first in the fourth generation) in the Grand Theft Auto video game franchise. It will be released worldwide on 29 April 2008 for both PlayStation 3 and Xbox 360. The game will be set in a redesigned Liberty City, based heavily on New York City and New Jersey.

Development:
According to Janco Partners analyst Mike Hickey, a financial consultant for Take-Two Interactive Software, around 150 game developers are working on Grand Theft Auto IV. He also remarked that Rockstar Games is "fully capable of ushering in an entertainment experience categorically superior to the prior cycle's GTA product."
Rockstar Games initially appeared to be committed to the original 16 October 2007 release date. However, Wedbush Morgan analyst Michael Pachter suggested that Take-Two may choose to delay the release of the game in order to boost its financial results for 2008 and to avoid competing with the release of other highly anticipated titles. Rockstar responded by saying that Grand Theft Auto IV was still on track for release in "late October".

On 2 August 2007, Take-Two announced that Grand Theft Auto IV would miss its original release date of 16 October 2007 contrary to their previous statements, and would be delayed to their second fiscal quarter (February–April) of 2008. Their stated reason for the date change was "due to additional development time required to complete the title." In a later conference call with investors, Take-Two's Strauss Zelnick attributed the delay to "almost strictly technological problems... not problems, but challenges." It was revealed that technical difficulties with the PlayStation 3 version of the game contributed to the delay.

On 24 January 2008, Take-Two announced that Grand Theft Auto IV would be released on 29 April 2008.
The game uses Rockstar's own RAGE game engine in combination with Euphoria[16], a game animation engine that will be responsible for character animation and the computation of a characters reaction to events in the game environment.

Plot:
Niko Bellic is Eastern European, between 28 and 32 years of age and has come to Liberty City to pursue the "American Dream". Niko was persuaded to move to Liberty City by his cousin Roman, who claimed in multiple e-mails to Niko that he was living a fabulous life, with a mansion, women, hot tubs and sports cars. Roman's claims turn out to be lies to hide his own failures, however, and in reality he only owns a small taxi business, which he wants Niko to work for.
Roman is the only person Niko knows in Liberty City to begin with, and is one of his major connections in the first part of the game. Niko is a tough character, whereas Roman is friendly. Roman is heavily in debt and a lot of people are after him. He desperately needs Niko's support, hence the reason he deceived Niko into travelling to Liberty City. They are constantly bickering. It is later revealed that Niko has also been avoiding other, as yet undisclosed, problems at home.
