It's really exciting that you're not afraid to play any kind of character.
I think you'd be great for this project I'm trying to start up:
Shotgun RPing. The RP plot we're starting off with may be a bit simplistic for your caliber, but I figure we should start small to see if this project could work at all. As you can see, our first session didn't go as planned... Anyway,the gist of the project has gone through a few incarnations, but so far it looks like this:
1. Loosely sketch out characters and plot.
2. Pick a day to RP the heck out of it!
3. Actually finish the RP!
I also thought it would be cool if we could finish the RP in a few 1-3 hour sessions. Maybe each person could have a 15-30 minute time limit to post to keep things rolling and the writing spontaneous. But in order for the RPG to take flight, we may need to plan what characters are needed and what plot to go by. That's where you come in!
So far, the Shotgun team is a bit... defunct. However, I've been in contact with Amethyst Knight, so Ame's definitely in and can start sometime next week. I'll PM the rest of the people to see if they have the time to do it too. But we just need at least two dedicated people to do this. And yeah, it would be cool to have you play an integral character to the plot.
On another note, If that doesn't suit your interests, you should scope out some RPGs that are just starting out, such as
The Almost Modern Fantasy. As an experienced role-player, you could decide for yourself what the story needs to keep it going.
