I'd say that I enjoy games because I find the mental exercise of escaping into some kind of fictional world incredibly relaxing and enjoyable. I have a very strong ability to empathise with fictional characters as if they're real. In this sense, games are just the superior form of entertainment. Better than books (which are in turn better than TV/film).
Even something as simple as mario, I find I can easily dissolve into the mushroom kingdom so the only issue in the world is collecting that star coin....
