Game: Grand Theft Auto IV

Niko Bellic is a complex and well-developed character who has been praised by critics for his maturity, moral ambiguity, and personal growth. He is a former soldier who was shaped by his experiences in an unidentified war, and he has a cynical view on life. After becoming involved with a Russian crime syndicate, he discovers that his unit was sold out to enemy forces. He moves to Liberty City to pursue the American Dream, but he soon realizes that his cousin's stories of luxury and riches were greatly exaggerated. He attempts to improve his and Roman's financial situation by becoming involved with the local criminal underworld, but he slowly learns to let go of his past and quest for revenge. As the game progresses, Niko works for various prominent fictional crime figures, and he eventually finds the traitor who betrayed his unit during the war.
