It's all about Respect.
Graphics: Pretty good, nothing next-gen, but pretty good. However, the game does lack different layouts for most of the buildings in the game. It can become repetitive to see the same place over and over again.
Sound: Great, feels like you watching the movie with the new subplot involved. Marlon Brando is perfect.
The Godfather: The Game is a great edition to the Xbox 360's library of games. Although it does take away from the game with the whole new character storyline (You), it is a great game.
