Definetly worth playing!
Graphics- I gave the graphics a 9 because the are not that great. During the cutscenes they are pretty good but the civilians and the environments get repetitive. They did do a good job on Tessio, Clemenza, Paulie Gatto, Tom Hagen, Vito Corleone, and Sonny though.
Gameplay- The gameplay is awesome. You can extort businesses, take down mobsters in hits. Rob banks. Plus you can travel through an almost perfect New York City from the 40's and 50's.
Sound- The sound is superb. They have Robert Duvall and Jimmy Caan reprising thier roles from the movies. They also have Abe Vigoda reprising his role as Sal Tessio. All the guns sound real and the music isn't half bad as well.
Overall the Godfather: The Game is a most-own for all fans of the movies, or just looking for a good game.
