I used to think RPGs were about stories, but I realized that they're more general than stories. If RPGs were derivative from story-telling, then they would just be an imitation of novels. Yet I know that RPGs have an unequivocal artistic value that is not reducible to novelization. And that this value in order to be actualized requires it to be specifically an RPG and not an adventure game or some other genre.
RPGs are to being a type to what flight simulators are to flying and to what city simulators are to being a mayor. RPGs are confused with novels because both of them have types but only RPGs simulate a type. EarthBound is an ENTj simulator, for instance.
But there's a difference between simulating a city and building one. If someone really wants to create a whole new genre of video games it should be one that allows you to make your own types like Spore allows you to make your own life.
