You might like Spirit Fall. Its an entirely homebrew system set in a post-apocalyptic New York City ravaged by actual, living, tangible demons. No one understands why or how, all they understand is the demons want their complete and utter annihilation. As a survivor in New York City, you would interact with others with one purpose: live to see tomorrow. I'd prefer it if you spoke English fluently and had a microphone. I run this game every friday and currently have 3 other players. Don't worry about the rules, they are simple and I can cover all of them in a few minutes at the most. Just PM me back if you are interested! I'm looking for one or two more players to join in. I know you said that you don't like post-apocalyptic settings, but I just wanted to toss my hat in anyways.
