The Walking Dead is an episodic adventure game with an emphasis on narrative and player choice.
Pro A lot of replayability
Resembling an interactive novel, the game plays out as a series of dialogue choices or decisions that result in specific actions. It's pretty interesting to replay the game many times and choose all the different ways of handling situations just to see how they play out.
Pro Stellar voice acting brings the characters to life
Voice actors deliver their lines with a lot of emotion, never feeling forced or fake. This excellent acting really helps draw you into the story and its characters. There's a lot of great chemistry between the various voice actors as well, resulting in conversations that flow well and sound very natural.
Pro Standalone story makes it accessible for all
Even if you don't read the comic or watch the TV show, you can still play and enjoy this game. It's a completely standalone story. While there are some mild easter eggs for fans of the show/comic, you can still understand the game just fine without any prior knowledge of The Walking Dead.
Pro Difficult decisions
The Walking Dead requires that the player make decisions throughout, these typically will be in the form of action or conversation options. In many of these situations there is no obviously correct or best choice yet these decisions must be taken in stressful situations often giving a matter of seconds. They can be morally testing as you can attempt to do what is 'right', what is best for the group or what is best for yourself as well having differing repercussions on how your character is perceived by different people.
Pro Engrossing storyline
The Walking Dead tells a genuinely gripping story which can be a testing and exhausting experience for the player. It is told through the interactions between people fighting to survive in a new world in which resources are scarce and threats can come from both the living and the undead.
Perhaps the major strength of the game in creating a compelling story telling experience is that it causes the player to care about the characters involved. This is an all too uncommon experience in gaming, and in The Walking Dead adds much greater meaning to the decisions which must be made along the way.
