Its kind of a cultural artifact of, I mean, without wanting to get too pretentious too quick, I mean, Wittgenstein tried to define game as part of his language games and couldn't, in fact he used it as this is one that escapes definition. For me video games are the same because I think drawing a line of what you call a game, um, what you call interactive art, or what you call a semi-interactive story, or a puzzle, its sort of an arbitrary decision, kind of a cultural artifact. Its what we call that.
