RPG's are taking over Arts and Writing. There are like seven of them and one that's not really one but . . .

Everyone left A&W, no one's continuing the RPs.

The most popular and most successful RP is Informal RPG. It's basically a free for wall with a lot of scripting and detail, it has a basic story and a currently absent plot. It's actually progressing rather nicely.

Here are the RPGs posted as of today:

Informal RPG
Raven Wings
Eidolon of Fate
Darkness Rising (called an RPG)
The Last Rebellion
Creating a Story (not actually an RPG)
The die is cast (which would have turned into a locked spam page if I didn't hijack it)

Some of them (like mine) have really good stories and anyone who wants to take a crack at it can sign up. I really don't think there is a specific group of players that would try to exclude anyone. It's kinda like writing out your own version of FF11OL.
