The storyline to the game is incredible. Every character is described beautifully and it feels like a film you are playing.
One of the best bits about this game is how realistic the action is, its not like your normal 3rd person shooter where it takes about 20 bullets to cut you down. Its a game where you have to think before you shoot.
The length of game play isn't too bad, I've played games that are shorter and games that are longer in this genre of game.
The reason why I've only given this game 3/5 is because there is no end of game free roam where you do whatever you please which a lot of people enjoy. Also there is no multiplayer and any gangster 3rd person game could be fantastic to play with others.
Basically the game has a fantastic 1 player storyline, after you have done that there is nothing else you can do, which is disappointing because this game could of been fantastic.
