Essentially is a basis for an RPG game that user's can play and create hosts and administer right here on the forum or (and I could be wrong about this) in the chatbox.
From what I can tell it would be a lot of work to set this up, and I'm interested if people would want to do something like this. We can design the RPG from the ground up.
Here is the tutorial on how to set it up, maybe it'll help you understand the limitations of what we can do with it.
