Well, this is awkward. As much as I love participating in these world-related threads, for once I have nothing to say because San Myshuno is the only world in my game that doesn't really have a theme (besides, you know, "people wanting to live in big city apartments rather than suburban houses"). I was going to make it all about gangs fighting with the police (using GT's club system), and even moved in the Landrgaabs with Nancy being a charity icon by day and a crime boss by night, but I kind of already have this theme with my rivalling churches in Newcrest, so... I don't know. No point in showing my map either because I haven't done anything extraordinary with the few visible lots, and the rest is just building shells anyway.
So I guess I'll just lurk around here to get some inspiration from what other people have done to San Myshuno.
