Game Developer Research, the sister service of game development news site Gamasutra, on Friday announced the release of its 2009/2010 State of Game Development Survey. It revealed a large jump in development for mobile platforms, with nearly 75 percent of those respondents targeting the App Store and its iPhone and iPod touch, more than double the support for the Nintendo DS and Sony PSP.

Support for mobile platforms was expressed by 25 percent of the 814 respondents, up from 12 percent last year. Those surveyed were drawn from a worldwide sample of Gamasutra readers, Game Developer magazine subscribers, and Game Developers Conference attendees. They were asked 55 questions about market sectors, tools they use, development plans, and more.

Other results: a little over 70 percent are developing at least one PC or Mac game, up slightly from last year; 41 percent are targeting consoles, with Xbox 360 leading the way, followed by PlayStation 3 and Nintendo Wii; and the proportion of developers working at companies with 50 or fewer employees increased seven percent from last year, while the proportion of those working at companies with 500 or more employees fell two percent.

The 2009/2010 State of Game Development Survey has a margin of error of plus or minus 3.4 percent, with a 95 percent confidence level. More information about the survey, which costs US$2,495, is available in the February 2010 issue of Game Developer magazine.
