So me and Jade have been discussing a few ideas about the city, and we've both decided on having each gang own businesses within the city, such as the strip clubs you were mentioning earlier, as well as restaurants, bars, garages, maybe even factories and warehouses. If you can think of it, your gang can probably own it. However, we'll be making a map of the city, as well as including in some neutral spots so that members of opposing gangs can interact with each other.
