One I have always  had a idea for, and always wanted to do, and I actually may try it if  I ever get  enough people interested in it, is an organized crime  role-play based on a fictional city I create,  that has its own , districts its own crime families and etc.  I call it City of opportunities, its hard to find people interested in it though where I rp at, and am not sure where to look for potential people to be honest.
