So addicting...
This is quite posssibly my favorite 360 game yet. I haven't been able to put it down, it is simply too addicting. Like others have mentioned, the voice-over work is phenomenal. Getting Marlon Brando, James Caan and Robert Duvall in the game is unreal. It really makes you feel like you're there. That said, this game doesn't even need the Godfather universe to be great. It's just icing on the cake. The game itself is so engrossing. The missions are fun and challenging, the open-ended gameplay of doing whatever you want is great, and the fun never seems to end. Just make sure you have plenty of time to play this. Once you start, you may not be able to finish.
