The models weren't bad, but it wouldn't be the end of the world if they made more than 6 per type. The rest is amazing!
But apart that, this game is fantastic!!!! Starting with the whole taking-over-the-city system. The interrogation/excoriation features are the most innovative things about the game, and even if the game fails making a nice GTA styled free-roaming (because the city, truly doesn't consist on lots of cool vehicle/character/buildings styles) The Godfather makes an excellent 3-rd person shooting game, with the lock-on feature and the possible weapon upgrades. Anyway all of the problems I mentioned won't be considered after emerging yourself in this game for a while.... But the real problem is the ending. After you've taken over the city they just make you don. Period. No cool cutscenes, it's really weird.
As a former Mafia player I might have put myself in the critics spot, but honestly I love this game. It gives you the sensation you're part of the 40-es, part of the family, the man behind the curtains, but at the same time, the man in the front line, the made-man who does all the work. If you're thinking of playing it, go ahead, but I also recommend playing MAFIA, and MAFIA 2 when it's out. They'll put you in a new dimension of 50-es Mafia wars.
