I have a great interest in playing a PbP, but haven't found one to play in, really.
I tried Aria's, a great storyteller and very ambitious, but some aspects of the style didn't fit with what I was looking for.
Other than that, I feel like there are rarely any new games coming up that don't just get filled up by guys who are already playing multiple games. I'm on the forums a lot and have plenty of time to obsessively check through posts, but haven't found anything open to try to be a part of.
That said, if anyone feels like they want to GM something, give me a ping.
