The platform holder added that 1,110 of these submissions had to be banned for containing inappropriate content, among other reasons, Joystiq reports.
Launched less than a month ago, Steam Greenlight is an initiative that enables developers to submit game concepts for the Steam community to rate. Those which garner the most positive feedback can then be published through the distribution service.
More than 949,156 Steam users have logged 9,998,476 votes on the games submitted, but only ten have been greenlit so far. An additional ten titles will be approved next month.
Earlier this month, Valve introduced a $100 submission fee to the service to discourage what it describes as "joke" submissions. All proceeds from this will be donated to the charity Child's Play.
Black Mesa, the fan-made project to remake the original Half-Life, was among the first crop of approved Steam Greenlight titles.
