Hahhh...it's complicated. Art is relative, subjective and has various definitions to different people. I'd say that numerous video games are art, while others aren't, which is the case with most mediums. I think Michael Jackson's music was art, while Lady Gaga's isn't (because she's a talentless hack who ripped off Madonna and relies on cheap sex appeal and gimmicks like dressing up like a pretentious tramp and calls it "fashion"). I absolutely adore Akira Toriyama's work, while I don't see what the big deal is about Picasso. I love J.K. Rowling's Harry Potter books, yet hate Stephanie Meyer's Twilight books. And the list goes on.
