Well I know that games can teach you a lot. For example, LA Noire taught me to be ********** when I thought there were no underlying details to be found. Mostly because one of my career choices is to be in law enforcement.
Other games test your decision making, even if the game is violent. For example, Fallout. You can make good choices, always help the good guys and do everything with honor, even when choices tempt you otherwise ("Messiah" rank at Level 30). Or, you can do everything evil, **** up megaton (a town with an inactive atomic bomb in it, though you can reactivate it) and achieve the "Devil" rank at Level 30. Of course, playing the same way can get boring, though I never bothered taking the evil route.
Another game where choices weighed heavily on the ****** was Fable, especially the third game. Be a "hated" king, but save the lives of many, or be a "great" king and save the lives of the few. That one was a curve ball, I can tell you that much.
These may be decisions that no one will ever have to make, but games can teach you what is right and wrong, though most of us know deep down which is which.
I have not heard of the game in this article, but it does sound like a great concept and I would love to see what it's like. I think it could be a great thing, and I wish the best of luck to the project.
