That art teacher should return their degree to where ever the hell they got it. Art is a form of expression just like any movie or book or painting. Deciding how the controls work and what choices to make.
Games offer a dimension of art that Movies could never dream of. In a movie you are following one pre-determined path through a story, but in a game you can take many, and see how those choices affect the game.
In a way an artist can express more of themselves through video games than a simple painting or movie. Lets say a game developer wants to communicate the harm that guns can pose in the streets, so the player in this game would have a choice of fighting in gun violence or becoming the criminal destroying the city with guns. In the first choice maybe he stops the guns, but at great cost to himself. In the second choice he becomes a gang kingpin and the world becomes covered in gun crimes.
