So, question for ya'll. Would you like to see more males or more females in game? And, would there be any interest in a character from something like, say, "Criminal Minds"? Or maybe "Castle", though I don't know if I could pull off anyone from that for sure. It's hard to find characters that wouldn't potentially interact heavily with those I already have. We'll ignore that I don't really need a third.

ETA: The feedback is uber helpful, I heart you all! Other possible fandoms I'm debating are Constantine (movie-verse obv, not comics), Doom, the Anita Blake: Vampire Hunter series, Skinwalkers, Supernatural, and maybe possibly Primeval. Any and all input is appreciated.
