Ready for some maths? 1,378,143 Kickstarter users pledged $US83,144,565 to game projects in 2012. There were 2,796 game Kickstarters launched. Of those, 911 were successful.
(Note that "games" in this context refers to both video and tabletop games. Kickstarter doesn't separate them.)
That dose of insanity comes via Kickstarter's cool "The Best of 2012" feature. Another fun dose of numbers: 2012 saw 2,241,475 people pledge $US319,786,629 to fund 18,109 projects. Staggering.
