The console port of Mafia wasn't very good, but the original (and cheaper) version for PC is superb.

But as aforementioned, the linear storyline does take it down a bit. If it was a little more of an open environment like GTA and had the customization of a game like, oh, say Jedi Academy where you can choose your destiny, it would be awesome.

Godfather game though...I'm not sure how they will pull it off without keeping a somewhat linear storyline to the Trilogy.
