There is a certain challenge to reviewing an episodic adventure. I mean, you need to set the benchmark in your first review, as no matter how good or bad the events in each episode, the overall game-play is not going to change dramatically from the first episode, right? I am pleased to tell you that the game-play and narrative present in The Walking Dead is so damn good, that it will take some serious missteps from Telltale in the subsequent releases, to bring this episodic series down.
Two things might have an impact on your experience of The Walking Dead.
1:) Have you played and enjoyed any of Telltales other Adventure games?
2:) Have you read The Walking Dead comic book series?
