Y'know, I think tushanshu hits most of your preferences? It's a slow-to-medium pace, AC's 15 comments/month, spread over three threads max, with the option to turn in more for IC rewards. The setting's fantasy with mild horror elements here and there, and there's an overarching plot that's really shaped by the playerbase. It's equally possible to be involved with that or to just kind of keep to the edges and SoL it up, whatever floats your boat and suits your pace. Also, almost all of the people I know will backtag basically forever.

We don't have a power cap, either. Unfortunately we have no castmates for you at the moment, and while we do have a network the text function is a little... less than useful at the moment, though I believe the tech characters are working on it.

And personally, I know I'd love a Zack-- I think he'd get along with a fair number of our cast. c:
