I was reading an article on Peter Molyneux over on Wired where he is discussing the development of Fable 2. The article has some great info on the development process. There are some great insights into what can and can not work. I was very intrigued with the following statement:

Molyneux says that through previous games like Fable and Black and White, he’s done extensive research of how people test the moral boundaries in a game, what they do if they’re given the choice to be good or evil.

“70 percent of people will be good,” he says. “20 percent will dabble with evil, then be good. Only 10 percent will choose to be evil all the way through. What’s fascinating is that this is very regionally dependent. It’s different from Germany to the U.K. to Asia.”

Also, what people are willing to do is totally age-dependent. “When people reach age 12-14, they become obsessed with evil,” he says. “The percentage of people who are good versus evil becomes reversed. It’s part of the way that teens’ minds are being reordered — it’s just a developmental stage.”
