So this is a pretty straight forward idea for a pbp. The basic concept is that the characters would start as a citizen of Nar Shadda, as one of the many shady individuals who live there. They would be the right down at the bottom of society, perhaps as a small time petty criminal, or perhaps working in a legitimate failing business. The options for back stories are still pretty open to the players creativity. Ideally the players would already know each other pretty well for convenience. Perhaps they were in a gang as children, or maybe the more criminally minded keep trying to drag the others to their level? Again, that's up to the players. The overall aim of the campaign would be to work your way up from the lowest levels of Nar Shadda to being the most powerful gang on the planet, any way you see fit. I have got one spot reserved already, but I could see this working well with 6-8 players. It'd probably be aimed at weekly posting as everyone has lives outside of this, so let me know if you're interested!
Idea for Crime Based rp on Nar Shadda
the setting and the general idea sound great.
as for the connections between the players - I would strongly encourage to discuss it with the players. sometimes it is better that there is as little connection as possible at the start of the campaign: e.g. they get together by chance or are assembled to do some simple (as it would seem at the start) criminal job.
This would let you all fill in the blanks of the back stories as you play and may offer additional plot hooks and opportunities to develop relationship between characters.
That's something that can be sorted out once there are enough players to play, I'm pretty open to most options at this point 
If anyone else is considering joining this, there is currently 3 players.
Sounds interesting, I've got a few ideas I could toss around for this type setting.
Yeah, think I've got an idea for a Trader/Politico. The guy working the money and scaring people into line with words (namely Scathing Tirade)
Sound good to me Feel free to link a SW sheet at some point.
I'll cook one up over the next day or so. Is this Knight Level or just standard starting character?
Just standard for this one. As you giys will be at the bittom of the food chain, it makes sense that you'll all have to work your way up.
Hmm, I am interested in getting involved. I got a Doctor that might be useful for this group.
Because if I've learned one thing about games like this, you always need at-least one person who can patch the rest of the group up when things go south. Doubly so if we're starting off at the lower end.
