I'm not sure if this has been tried before, or if it will even work. But I think it's an interesting idea and I think it'll be fun... Remember, I don't typically do this, so I might not be doing it very well, but I'm trying...
So, this is basically an rpg. But unlike other rpgs on this site, it doesn't require fixed players or someone to control the story. There is no character sheet, and results are based solely on decisions and not stats or items.

So, the next person who posts starts the story, because I don't have the time right now.
