I guess such a prequel with Bill as one of the main characters and playable character would be very nice! But I'd also be very interested in other, new characters ... maybe one, who turned into hunters or other people who struggled over a few years before becoming cannibals, like David's men. I'm interested in characters development and the background stories of a few survivors would be very cool - to see who they were, what they become and how ... I mean the characters have made it through a lot of "ugly stuff" and it would be as interesting as shocking to behold their development from "normal guy" to "WTF, who IS THIS FREAKING GUY?"
