PC's Creating their own Gangland, Like D&D's Kingmaker but for Shadowrun! Options

[Mystweaver]

Hi all,

Long time since I have posted last, but I'm finally going to get back to shadowrun after a long break playing other games such as Pathfinder, Dragonstar & Dark Heresy. All much fun.

Though I've got a while to go, I've volunteered to GM Shadowrun 4th Ed. My group haven't played it yet (always been core 3rd Ed fans).

At the moment we are playing Pathfinder D&D in the Kingmaker campaign setting. For those of you that don't know, this is ia campaign where you create your own kingdom and through a series of random encounters and an on going plotline go about your business as a Baron-Duke-King as you expand your kingdom till the end of the adventure path.

As our group seems to be enjoying this type of sandbox semi-linear style play, I was thinking of doing the same sort of thing in Shadowrun.

And so, I am wondering if there is anyone out there with and pervious experience or can link me to any particular resource that might give me some foundation for working out how my PC's can take their street gang and expand out in Seattle to create a funky criminal empire.

I would be happy for this to be gritty or abstract. Whatever works really, but knowing my players they will think of all sorts of things to get up to and the last thing I want to say is "No you can't do that". Whether they are going to get into BTL dealing, pimping, money laundering, racketeering, or whatever, I want to be able to figure a background mechanic to allow them to administrate this relatively quickly while being able to get out on the streets and do deals, smack some people about, get attention of more powerful people and getting hired or attacked as and when appropriate.

Obviously skills will be taken into account so the players will be able to destroy, kill, intimidate or negotiate with anyone they like. Clearly I'm being ambiguous but thats just the nature of RPG eh!

Any help would be greatly welcome

Thank you all in advance.
