My girlfriend's art teacher said video games are not art. Do you agree?

The way the art world sees it, if the piece serves a function or purpose its not art. Kojima, the conept artist and my illustration teacher all agree on this.

BS. All art serves two key purposes. An emotional response and making money.

Can you make a video game without gameplay? can you release a black screen display for 5 minutes for free digitally and call it a game? because artist like painters and movie directors can show a black canvas or a 5 minute short film of just a black screen and call it "The Afterlife"

If Kojima released a black screen for 5 minutes for free people would say "its not a game". Video games are not art.
