I've only played a few hours of The Walking Dead so far (not even finished with part 1), but it's definitely a game that shows a lot of promise. The game has seemingly far more focus on story and dialog than puzzle-solving or exploration, which can be a good thing or a bad thing for an adventure game depending on the context, but in this case, it's definitely a good thing. The game continuously emphasizes the importance of your actions and the affect they have on the story; some characters live or die depending on what you choose, and I can imagine that things can end up very differently depending on what you choose. Of course, it could all be an illusion, broken upon a second playthrough, but it's at least a very good illusion: choice seems to be present. The dialog system supporting that choice is also exceptionally good: taking a cue from Alpha Protocol, the game presents your options on a timer, forcing quick responses and snap judgements, this leads to sometimes interesting, sometimes unintended consequences, but it's engaging and almost always interesting. This seems like a game where you should never go back to "correct" your mistakes, just let the story play out and see where it takes you. At the end of the game, if you want to see how things could have been different, go back for a second play through and change things that way. This is how I try to play all of my choice-based story-driven games (The Witcher, Mass Effect, Deus Ex, etc), and I find that it leads to a much more interesting experience than trying to do everything "perfectly" the first time through (that's what multiple playthroughs are for).
