It is hard, because people are scared of messing up and being judged (do not get me started on my dislike of live and let live in the RP world). So they stick to bland slice of life and no one is into that enough and it all falls apart.
I just like the idea. Going undercover, maybe for years, who is the man and who is the persona, that kind of thing. I think spies could be fun.
I don't know how it could work but I love that idea too!
