They're interactive stories for the most part. Not a lot of gameplay involved. I don't know how good The Walking Dead is because I hate everything about The Walking Dead, and I haven't played their Batman or Game of Thrones games, but I can tell you that The Wolf Among Us is awesome.
"Your choices matter" except nothing you do matters, the stories are pretty unoriginal and formulated, there's no gameplay and they'd rather explain the story in a hallway than show it. Telltale hasn't made a good game since the original TWD, their games are really just selling because of the licensed content.
