No video games, like all games, are not art. Soccer is not art, tennis is not art, hopscotch is not art. Games can INCLUDE art as a part of their presentation. The pieces and board of a chess set might be elaborately decorated to the point where we can call them artworks, but the game of chess itself is not art. Likewise, a video game might include many pieces of art such as music, sprites, etc, but the game itself is just a set of rules. In most games, such as chess, human brain power is used to process the rules of the game, but video games are very complicated games, therefore it is processed by a computer instead. But if you were an infinitely smart person you could play a video game in your head just like how you can play a game of chess by writing down moves on a piece of paper, no board or pieces needed.
