You are using a very binary black and white form of logic here, simply because it's one thing it cannot be something else as well. That logic is incredibly flawed. For example I have a fake plant sitting in the corner of my room, however it's not just a fake plant it's also a decoration and, if you really wanted to get fancy, a interior design aesthetic. Yes video games are games, but they are also entertainment and it's not out of the realm of possibility that they could also be art; esp. since art is largely subjective. And really what difference does it make to you? How does video games being classified as art detract from your enjoyment of them?
