I think I assumed a little more than I should have about how much people would know about Ebert's argument. No, the customer changing the art has nothing to do with it. The audience complaining is what this was in reference to. The argument Ebert made is that if the ending of a game is up to the player it's not the result of an artist's vision. This is even one more step from that, not only do your actions as a player affect the ending, the players don't like the ending they got and the company is going to change it. I don't know how I would personally feel about Michelangelo changing the Sistine Chapel in response to tourists complaining about it, which is more like what this is.

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.
