I presented this entire stack in-class in 2 minutes, so imagine me talking really fast and spending about 10 seconds on each slide. In my view, it's both an extension and better formulated version of my "Philosophy of Game Design" series. It'll probably be a Half-Life 2 mod, coming December 2010.
I'm not proposing this as dogma. Many games use many different lenses.
BUT we can look at the philosophy of education to help us design educational games, or we can look at Marxist aesthetics to help us design satirical games, or we can look at unreadable Poststructural stuff to help us design games as formal rhetoric, etc.
