Being an artist, I'll drop my two not so worthy cents into the mixing pot.
Art for Art's sake is okay. When I make art, whether it's a picture, or a short story, or even an interactive medium, such as games, I make it for me. Sure, other people can download it, or look at it, or do whatever they want with it. But the purpose of it's creation, is because I wanted to make it. Now, if other people don't understand what it is, or feel that it's pretentious; Honestly, that's they're problem.
That said, I agree, certain things and labels have expectations associated with them. A book should presumably have words, and pieces of paper, and plots, or, themes, crescendos and such. But if someone wants to take it outside of the norm, throw a little trickball into the court, by all means. So if someone draws signography (for lack of a better word) on a toaster, to make a story. By all means, I'll consider it a book. 'Specially if when you pull the handle down and it starts toasting, it burns the rest of the story onto your toast.
That'd be sweet.
As for games, I consider them on the 'fun' line. If you want to make it an artful experience for the sole purpose of art, then, label it art. Art Games, or Interactive Art. But if you want to make a game, a videogame, or whatnot, then, make it fun. Exciting. Meaningful. This only applies if they want people to understand what it is by it's label. So back to my previous point, I don't really care what people label their art. It's their art. And they shouldn't care what people think of it either.
Just my two unmeaningful cents.
