Given that we can use many of the lenses used in discussing other art forms to discuss video games, it seems a safe assumption to consider video games an art form as well. You may not be able to judge or measure them in entirely the same ways as other art forms due to their interactivity and agency. This does not mean that they are not art though.
Art by its very nature is about pushing the limits and boundaries of what we consider to be beautiful, creative and artistic. Philosophers mourned the loss of the spoken monologue when writing came around. Illuminated book artists and scribes decried the vulgarity of the printing press. Photography upset painters, and the ability to record music upset musicians. Cinema and television no doubt upset live performers and theater troupes. Video games are simply the next link in the chain. Each new art form or technology brings out the scholars lamenting the inevitable death of the old, and yet we still enjoy them today. When I was young I remember quite well the ongoing row over modernists junk or “found” art sculptures. The average person simply did not understand the movement, even as the critics lauded it. Today many people are fervent supporters of the upcycling movement, turning trash into art or into utilitarian objects. Personally, I enjoy the repurposing of pallets and old doors into things, although I am not a fan of my boyfriend’s toilet gardens in our back yard.
Already we are starting to see rare video games becoming collector’s pieces, often fetching prices in the hundreds or even thousands of dollars. Researchers and collectors scour yard sales, flea markets, and dumpsters hoping to find unreleased and lost games or studio ephemera.
