Valve recently pressed the go button on Steam network's Greenlight program, which seeks member advice on what games the company should develop. It seems a natural development, given the popularity of crowd-funding platforms like Kickstarter and Indiegogo. Greenlight, notes an post, functions in much the same way, except that it is only for Steam games. Briefly, a developer uploads screenshots and a synopsis of a game and members of the Steam-using public get to voice their opinions. It amounts to a simple, effective way to gather market research from an incredibly large focus group. It's a clever development. Given its size, the Steam community makes a formidable resource – but the fact is that the vast majority of users are on Steam to play games. The social aspect has always been something that has been lurking in the background. Greenlight has the potential to drive a great deal of interaction and may see members spending more time in the community between games – and, ultimately, that drives sales.
