Not sure if we've got any RPs that might interest you then. The RP we've got a PC in is a simple Stargate RP. So far only one "side", though there are many factions and facets to it.
The RP we're GMing is a star wars RP with both Jedi and Sith PCs. So there are, to some degree, teams in it.
Both of them tend toward long posts.

If neither of those (linked in our sig) fit your interests, we'll wish ya good luck in finding ones that do. There's enough RPs here that such should be easy.
