american's activity rules are monthly based and require two posts: one for members to interact with and one that provides insight to your character (typically a narrative, from what I'm seeing, and >= 200 words). All the characters mine has reached out to are engaging (to varying degrees, it depends on who they are as an individual) and they seem three-dimensional. I haven't encountered any cardboard cutouts which is really, really wonderful. I can't speak too much to the storyline development OOC because I went in pretty organic, but I've noticed members coming in with family, coworkers, partners, rivals, etc. etc. and the posts people make in ~pbads, especially for brand new characters, are fairly active.
