Then video games qualify. This is an article which argues that something does not satisfy the criteria for art. So when he he invokes his ability to exclude mathematics from the definition without any justification, or at least without appealing to any reasoning whatsoever, and then using that conclusion to assert that games aren't art, all he is doing is demonstrating that his essay should have been much shorter. The same unqualified assertion that applies to mathematics would apply to videogames, and he needs go no further than the thesis.
