Ugh,definately not TellTale Games. Once you've played one of their games, you've played them all. The plot and character changes, but the gameplay is always the same. I would much rather play a roleplaying game, with Sanderson's quite unique world building and magic systems it would be a shame to just have all the action be about pressing right button at a right time (aka TellTale Games way). So... someone like Obsidian Entertainment could work,
