In theory, yes, but let me know if you find out how to do it in reality. Because we live in an age that's pervaded by fear. Gaming is a way to deal with what we don't know, but at the same time I wonder how much gaming would help to resolve the problems surrounding us, or the things that are uncertain by definition. Personally, if I have to confront something that frightens me, what helps me is remembering to maintain a state of openness, rather than gaming: even if I'm not sure what results I'll get, I try to calm the part of me that goes straight to the worst scenario. So really, let me know if you discover how to use gaming on a large scale in that way!
