I really don't think its that far fetched. I'm a huge fan of the godfather and think i have a good idea to how you could make it into a video game. So first off i think it has to take place in the 30's during the Five Family war and could have you running assignments for Clemenza or Tessio or even both. It would be great b/c you could help build the Corleone Empire by running hits and as the game goes on you become more and more important to the family and ultimiatly become a made member and you get to meet the Don. This is just an idea and i would love to hear people elaborate on it to your own likings.
