Having heard postive feedback regarding it as a downloadable episodic title I thought I would give it a look myself and here are my thoughts on the first episode of The Walking Dead.
What I really liked were most of the characters in the game it felt like you really cared for them and you were given some difficult questions to answer as well. What I also liked was how it looked as a downloadable title. My god the presentation is very good as well. I also liked the atmosphere and also you didn't have firearms that you had to basicaly use certain tools to defeat the monsters in the game. It felt like it had a bit of stealth so they couldn't see you and you also had to make a really tough decision at the end of the episode between saving 2 people. I also liked the stats at the end of the chapter showing you what other people did who play this game. Plus the little teaser at the end was like a good build up and wanting you to see what happens next.
I might do an Episode by Episode update of this game because I am really liking it and I just bought Episode 2 off the Playstation Store but haven't started it yet.
