Cormoran: I completely disagree with this.
I think people with this complaint have just missed the new type of gameplay TWD has brought about, that is Emotional Gameplay.
It's difficulty lies in the decisions you have to make and requires you to be emotionally invested in the story and characters to shine (which ofcourse requires them to be very well written and acted, it's a very big gamble to be able to hit these out of the park).
I don't see it as undermining gaming, but bringing about an evolution in gaming. To me that's why it's getting all of these accolades. It's not something everyone understands yet, or realises the medium is even capable of (like Roger Ebert for example) but I'm glad that it's something the industry has understood and taken notice of.
StingingVelvet: Those decisions and such are presented like cutscenes though, in a movie-like fashion. It's not presented as a game, as interactive, it's like a DVD menu choosing which scene to play.
Think about Half Life 2. It's story is told in a fully interactive way, most of it not even spoken but more experienced. Think of an older Western RPG, which presented it's story through discovery and flexible dialogue and offered choice through action without railroad signs.
Walking Dead is an interactive movie. And that's fine, I would probably even enjoy it. It's not progressing gaming storytelling though, it's killing it.
Half Life 2 is not told in any interactive way whatsoever. Gordon doesn't react at all, let alone in any interactive way. He gets a mission and does it, while it's hidden nicely it's no more interactive than the story of Doom or Wolfenstein.
I'm guessing you mean Morrowind when you mention the western RPG and I think i've found why we're butting heads here. For you the storytelling comes in something you make up in your head, you react in gordons stead, you roleplay the reactions in the wiki-esque information boxes in TES. But that's not what game storytelling is about for me. There's a saying in movies; show, don't tell. that applies to games too, the game should accomplish bringing about the story instead of expecting your own imagination to. I could use my own imagination to give super mario bros. a harrowing and emotional rollercoaster of a story, but that doesn't make the game itself anything more than a great side scroller, if it want's to be more it has to do that itself.
