Your definition seems to include bizarre sentences like “When the creators can (maybe ‘sometimes do’ would be better here) change their work after they released it, that work is not art.” Maybe you qualify sentences like that further (and propel it to ever more bizarre heights) to only include changes made because of public pressure.
Throughout history, many artists took commissions. The ceiling of the Sistine Chapel was a commissioned work. Do you really want to tell me that if we were to find out that Michelangelo was asked by the pope (the customer) to change something after he finished and did so, the fresco would no longer be a piece of art?
Stuff like that makes me never want to use the word art again. Videogames as works to be appreciated by others most certainly do not have to hide behind any other works made for the appreciation of others.
Obviously this is not black/white and everybody has their own definition of Art, I was just pointing out how this connects to the pretty major controversy from Ebert's pronouncements last year.
The justification for that kind of mindless definition just makes no sense at all. The artist sets the parameters and all possible different endings (if they exist at all, most games don't have something like that) are obviously part of the artistic vision. Someone had to make those endings. The player certainly doesn’t. Why can the artistic vision only encompass a single way of experiencing a work? What’s the reasoning for that? Why can’t the artist offer multiple ways of experiencing a work and let a player (in this case) pick? Because doing stuff like that didn't used to be possible? Why add something as ridiculous as that to the definition?
It boggles the mind.
(Oh, and I was picking the pope because he is the customer - just like in this case customers of the game are complaining and potential customers say they want things changed before they buy. Talking about tourists in this context makes no sense at all.)
If I'm in a band, and I make some music and the fans don't like the buzzsaw sound, and I then remove it and remaster the track, does that mean that my song wasn't art in the first place?
