The main character is an eastern european man called Niko Bellic. Niko is not customizable as it was possible with CJ in GTA: San Andreas, but you'll be able to style him with different outfits. The reason for this is that after they got Niko's physics and look 'dead right', it was difficult implementing features that will allow the customization of his body. He is the guy that you may have seen in the GTAIV trailer released at the end of March. The basic storyline is that Nico has been persuaded to travel to Liberty City by his cousin, Roman. Roman claims to all up in riches, living the nice life with 15 cars, 4 hot tubs and plenty of beautiful girls to go around. Turns out Roman isn't what he seems to be making himself out to be....Nothing he's said is true. Even though they don't always get along and are constantly bickering, Roman becomes an important guideline for you at the beginning. Being the only person in the entire city that you know, he becomes the main source for connections at the start. Roman is in fact in a lot of trouble with a lot of people who are after him for unpaid money and various other forms of debt, and he needs Nikos help!
