Wow, I only just noticed this subforum! I've been a roleplayer for over two decades.
Currently, I'm running a game I'm building from scratch called
Heroes of a Dark City. While the setting is not frightfully original, the general concept is more interesting. It grew out of a necessity to run a campaign that was suitable for a group that varied a lot in size and composition.
You can find out more here:
What is Heroes of a Dark City?.
At the bottom are links to some resources. I'm nearly done with a basic description of the setting and I'll soon be adding some of the first origin stories based on our early sessions. An alpha document on the mechanics is also in the works.
The project is still in its cradle, but anything I create for it will be available for free.
