This is why I'm happy that I've always been a loner. I don't think I would fit in a PRG very well at all. When my brother asked me what sort of person I would be I just told him I had no idea. Further prompting revealed I would be 'a mysterious guy', because frankly I don't have any excess character flaws or social maladies to abuse into a stereotype (I don't).
You would have to use my online persona, and make me into a noisy person. That's about the best I could come up with :p Since there's no room for a noisy guy, PG's sitting this one out :D
