Do you know the number of Video Games Ever Published?

Sure, there is no exact number, as games development keeps going on, and hopefully never comes to a halt. However, you can estimate the number of published games already around us. A few interesting lists for your reference:

List of canceled games http://en.wikipedia.org/wiki/List_of_cancelled_video_games

List of vaporware http://en.wikipedia.org/wiki/List_of_vaporwares

With more focus on quality than quantity, the growth in the number of releases on consoles is less significant now, comparing with the period when Playstation, Sega Saturn and N64 were still major consoles in the market.
