I'm sure, if you set the right rules and guidelines, you could pull off a literary RPG in AMW. Just make sure that you don't attract the wrong people, i.e. people who post one sentence every other post as their contribution to the story.

I totally agree with you ^^

And people I know call literary RPG Role Playing. I've been in lots of RPs before and you can interact with everyone.

And I'm not saying RPGs are rare. I'm saying RPs are because we are so focused on one person(basically) instead of everyone playing. RPs revolve around MMO and gives us the opportunity to read everyone's post in case they are acttually interacting with us. Plus, we can make more than 1 characters at a time if they let us.
