The number of indie developers in North America is on the rise, according to the Game Developers Conference's State Of The Industry survey, with 53 percent of respondents now calling themselves "indie." The 2013 survey also found that 51 percent of these indie developers have been indie for less than two years, signifying that 2012 saw a notable indie uprising in the industry. Additionally, 46 percent of those surveyed said that they currently work in companies of 10 people or less, while only 24 percent worked with a publisher on their last game. And what of the games they're currently working on? As it turns out, 20 percent of respondents are working with a publisher on their current project. The graph below shows how developer interest is weighted towards platforms that are friendlier for independent game development (click for larger version): The Game Developers Conference polled more than 2,500 North American game developers who attended the conference in 2012 or plan to attend GDC 2013 in March about their development practices, revealing several notable trends with regards to platforms, money, team sizes and more. The GDC intends to field a similar survey each winter, in advance of the conference in San Francisco. Organized by the UBM Tech Game Network, GDC 2013 will take place March 25-29 at the Moscone Convention Center in San Francisco, California.
