I've heard that "The Godfather" is quite lifeless and lacks a soul.
I'm not expecting much myself (will hold out for Mafia II for that), but one thing I've read that intrigues me is that the game actually follows the movie very closely, and really doesn't mess with key scenes at all, so they're all in the game.
Meanwhile, you're not playing one of the key characters in the movie - more of a background personality - so the result is that you frequently find yourself playing along and then suddenly realizing that you're now taking part in one of those classic scenes from the film.. As a fan, I think that could be pretty cool, actually.
..except, of course, for any of the scenes featuring Michael..

Good thing he's not really an important character

Or a recognizable personality

I'm sure it'll hardly be noticeable
Anyway, as I say, I'm not really expecting much, but I still might give it a whirl if only for the chance to recreate some of those scenes..

I'm not even angry. I'm being so sincere right now, even though you broke my heart and killed me.
