This is the main character of the game, and is the role played by yourself in the single player game. Tommy is a cab driver who, due to unforeseen circumstances, ends up working for the Mob. A nice guy who had a hard childhood, he ends up doing all kinds of things for the mob that would make most of us cringe. However, he does have a conscience, which from time to time leads him in the opposite direction.
Norman is a tough Detective, a typical representative of a detective of American tough school who has a bit of a reputation as a lout, he dislikes everyone. Tommy is narrating his life story to Norman, and it must be said that it isn't at all easy for him.
The Boss of the Family that Tom is working for. Salieri is a man who's lived through a lot, and there aren't many things that make him lose his cool. He is one of those Mafiosi for whom the money wasn't the main reason for building up his position. Although he will stop at nothing to achieve his goals, his first course of action is not necessarily the most violent or aggressive one. He is friendly, but when it comes down to it, he can get really angry. His motto is 'business first' and friendship must be put aside sometimes.
Tom's gang-leader. He?s a small guy, full of energy. He is a choleric and sometimes behaves quite unpredictably. However, when he takes a liking to someone, he is the truest friend there can be and is always reliable - if he isn't busy causing you some trouble, that is. Paulie and Tom like each other immediately and become good friends; they work together quite often.
Another of Tom's colleagues. He is a big, friendly guy, with a nice smile. In spite of his size, he is timid and a little clumsy, and doesn't talk much. He often works with Tom and Paulie, and they are good friends.
