Mafia strategy

Good evening, gentlemen. Advise suitable strategy, mafia, gangsters, illegal business, bribery, murder, etc. are currently playing in the excellent Omerta and very happy with it, but honestly is something the game lacks. The enemy gang of the gang. It is not a large family. A kind of diplomacy in the game. Gangs only cope with murders and shootings. Not to mention the game Godgather 2 where playing for the prestige and cunning of don, and for washed-racketeer, which solves any problem of showdowns and gunfights. I always thought mafia family companies are incredibly clever people who not only know how to shoot, but also know how to speak well, negotiate. Maybe someone knows a similar strategy? Not only with guns waving, like dumb cattle, but also to think and to cheat. There are such strategies?
