I modded Slate Tundra for dark.
I spent hours on the city's roads and stuff, and with the old one I spent a week or so making the essentials.
I know that other people don't play CityRPGs much but you'd expect something like this to attract more idiots. If anyone wants to come, the server is up right now and will be down when the internet crashes again.
Making a city RP that isn't on a slate map may work out. I always liked kitchen and bedroom.
I tried kitchen and got pretty far. Bedroom is limited.
