The Walking Dead is an episodic video game series based on Robert Kirkman’s award-winning comic books. The dead have risen to feast on the living, and the living cannot be trusted. The story you experience in The Walking Dead is driven by the choices that you make. Because of that, your story could be very different from someone else’s. (from Reddit)
I remember playing this game a couple of years ago. It is a good illustration of the central idea I was trying to get through to my audiences: everyone makes choice based on his/her self-interest and value system. As a person who has no knowledge of the future, there is no right or wrong choices; it's just whether the consequence of your choices servers your best interests. Whatever choice you make, as long as you are still alive, life goes on.
There are several great elements in this game. One is that it successfully combines the graphic with the choices for the players without making them feel bored. The other is that it provided a reflection system for the player's choices, i.e., one gets to see a summary of what other players chose under the same circumstances.
I am a little torn between ideas right know, so I consider this logic model to be a placeholder for now. There's still a couple of decisions to make, on whether to focus on history or general perspective taking, 3D RPG adventure game or text-based non-linear story telling game, and students or any interested gamer as audience. The design in the future could change drastically based on my decision on the issues above.
