You like it? I do!
I started (officially) my Pbp today. I mean, just a few minutes ago, really, so not much to report yet. I do really like the Spirit of the Century rule for chargen that I borrowed; each player writes for his character a small vignette that represents a novel or story that happened in the past; his own pulp adventure novel, if you like. It's not supposed to be long; a couple of paragraphs tops. Kinda like the dust jacket or back cover blurb on a real book.
Then, when everyone's done that, you randomly assign that character to two other players, so that everyone has two players and everyone was picked twice. They in turn write a couple of sentences emeshing their character in a supporting role in the backstory vignette of another character.
This way, every character has a connection to, at a barest minimum if the randomized picking comes up bad, two other characters in the group, more likely three and possibly four. This 1) gives them a reason to work together, because hey! they have in the past and know each other, and 2) have some instant roleplaying hooks to latch onto within the group.
So far, I'm not 100% sure how it's working out, but it was fun to try anyway. I like the process and will probably use it from now on.
