Hey, Telltale! I have another idea! :D
You should make episodic games on: Doctor Who. :)
Doctor Who, a british Sci-Fi show that relies on wits more than fists, would not only make a great adventure game, the episodic format is great for it, since every single episode of the old series was a multiple-episode storyline.
There was recently an announcement that a company was making a Doctor Who video game, but I'm almost positive it will fail. Will this give Telltale a chance?
