This pretty much summarizes everything that is currently wrong with the video game industry. This endless push to turn games into movies, this push to recognize games as "art," is all about one thing: validation.
Video game designers and producers need to get over their paralyzing sense of guilt. You're a toymaker. If you feel uncomfortable about being a toymaker, then find something else to do with your life. Good Lord, tt's not like you're building bombs.
In fact, I think video games stopped being fun right around the time this industry started pushing this "games as the new cinema" meme.
