Gonna attempt to finish Caira and Quantum tonight. I don't think I'm gonna finish before my thirty day deadline, and I think I'm going to use up the word limit, so I might collaborate with the Mods to create a mega-mega-thread.
Bill is in the Dead By Daylight DLC. They bought the rights to Bill's character from Valve, or maybe just struck a deal. Either way, he's now a playable survivor in DBD.
