The Walking Dead is the ONLY videogame I consider to have a story the quality of which rivals other entertainment media, both in terms of the way it's presented and the characters that take part in it. That it was a financial success and won game of the year means other studios will start to follow suit, and that is a very good thing because it means we're going to see more of the same, and future projects that improve on that formula. Finally, videogames are coming out of the cheesy, unsophisticated 80's action/horror movie rutt they've been stuck in for the last few decades.
Of course, the more "gamey" games aren't going anywhere, so people that decry this change as a bad thing really have nothing to worry about. We'll still be able to shoot mindless hordes of things in the latest Serious Sam or Painkiller iteration any day of the week; I'm just glad things are getting better on the story side for those games that want to go in that direction, i.e. Tomb Raider, Last of us etc.
