Want proof that video games have gone mainstream? Look no further than ex-vice president Al Gore, who called gaming "the new normal" at the Games for Change conference at New York University.

Gore touched on a number of topics during his discussion, including the concept of "gamification" and his own relationship with gaming (turns out the last game he played seriously was Pong).

"This is a very large, extremely significant industry, with a radically diverse and growing audience of players on all kinds of platforms," Gore said.

Gore also shared the four qualities that he thinks makes for a good videogame. They include the need to be immediately engaging ("Within the first five seconds," Gore said); make it possible to "win fast"; be visually consistent, and offer plenty of badges, levels and awards (as well as "major moments.")

An interesting take by the former vice president on games. Do you agree?
