In Grand Theft Auto 4 you take on the role of Niko Bellic, an immigrant from Eastern Europe with an ominous past. Persuaded by his cousin's promises of a fresh start and a better life, Niko relocates to Liberty City, USA -- the worst place in America. After making the move to Liberty, however, Niko quickly realizes that his hopes of "living the American Dream" may never come to pass... and that things here may not be so different after all.

Although Liberty City may not differ greatly from Niko's homeland, being different and standing out is definitely a major theme with Grand Theft Auto IV. While GTA: Vice City and GTA: San Andreas were considered to be part of the GTA III trilogy (same graphics engine, similar characters, similar mission style, etc.), Grand Theft Auto IV is considered a fresh start for the GTA series, focusing more heavily on realism and storytelling than in previous titles. This is why it's been dubbed GTA4 and not GTA6 (as many had originally anticipated), even though it's the sixth major title in the series.

GTA IV follows the release of the hugely successful GTA: San Andreas (which was released for PlayStation 2 in 2004, and then later for PC and Xbox during 2005) and also marks the 10^th anniversary of the Grand Theft Auto franchise. With Grand Theft Auto 4 being the milestone that it is, Rockstar Games has been working overtime on perfecting the game. According to Janco Partners analyst Mike Hickey -- a financial consultant for Take2 Interactive -- approximately 150 developers are currently working on GTA 4.
