What is a good system to run a game about crime from the criminal perspective mostly?
I have not found the perfect one for me yet. When it comes to long running games.
Important to me would be some kind of mechanic that represents the social interactions and alliances. Be it the organized crime syndicate of the Wire or the Godfather or the group of experts you get together for a heist.
In that direction something that works with trust and betrayal could be nice.
Also making plans should somehow be rewarded and fun. Could be intrigue, a planned heist or a hit on someone.
So what systems would you use or have allready used for a crime game? Did they work out? What subgenre did they emulate especially well?
