I, for one, would LOVE to have a DLC where we get to play through a short amount of all the character's backstory before and right during the start of the apocalypse. We could see how Kenny, Duck and Katjaa lived before the apocalypse, and then play through the scene at the gas station where they discovered the apocalypse had begun. Also for doug/carley, lily/larry, clementine/her parents, ect. Obviously we already know how Lee found out about the apocalypse, but i'd love to see his life before it, teaching at a university, and maybe play through the fight with his wife's partner.
What ideas do YOU have for future DLC?
P.S. the reason this is in the "Spoilers" thread is because people will most likely write spoilers.
