IMO what needs to happen in regards to teaching games at schools is to look at them from a cultural and/or artistic standpoint. Analyze video games, both popular and unpopular ones, to draw from it information based on what made certain things work better in certain games, while at the same time allowing for a analysis of culture and society and why games like halo sell so well, while okami does so poorly, at least in Western, specifically American cultures. For all intents and purposes it should be used as a Humanities type class, with maybe a few sections based on what has been deemed necessary to make these games. But hey, what do i know right?
