This is admittedly REALLY pedantic, but there were some non-game cartridges released for the NES and SNES, such as Taboo: The Sixth Sense (a tarot card reading program), Miracle Piano (a program for teaching how to play the piano), Mario Paint (a basic music composition and drawing program), and a modem add-on for the Famicom that supported banking, stock trading, and horse race betting.
