Greenlight, Valve’s community-based launchpad system, is up and running.

The service allows developers to post information, screenshots, and videos of their game in the hopes of gaining enough of a following that their game is picked up for Steam distribution.

A plethora of quality games are already on the service, including multiplayer FPS Rekoil, thriller Slender Man, and the much-anticipated Towing Simulator.

"We've been working on this feature for the last few months with the input from a group of indie partners, and the response has been extremely positive," said Valve's Anna Sweet.

"With the additional help of beta testers, we are able to launch with a solid line-up of titles for the community to start viewing and rating. And, as we've done with all Steam features, we intend to continually grow and modify Greenlight as more and more developers and community members have a chance to get involved."

FIFA 13 and Counter-Strike: Global Offensive also have Greenlight pages, and the speed of their disappearance should be a good test of the voting system’s robustness.
