Good luck finding a cityrpg that is not broken. As I mean by this.. all public ones are broken
Someone will have to make one but no one has any idea on how time consuming it is, and people wanting different things in a "cityrpg"
I have one that is not broken but it is very imcomplete and I won't recommend using it. Someday I will actually complete it but who knows when. CityRPGs are a huge pain to work with.
