Steam Lets You Give The Greenlight
Steam Greenlight is a new system that enlists the community's help in picking some of the next games to be released on Steam. Developers post information, screenshots, and videos for their game and seek a critical mass of community support in order to get selected for distribution. Steam Greenlight also helps developers get feedback from potential customers and start creating an active community around their game as early in the development process as they like.
Over the many years that Steam has been selling games, the release rate of games on Steam has continued to grow significantly. But given Steam's existing technological pipeline for releasing games, there's always been a reliance on a group of people to make tough choices on which games to not release on Steam. Instead of relying on this internal group, Steam has decided to rely on the community.

An example of one of the dozens of games already up on greenlight is Rekoil - a "back to basics" shooter without killstreaks, perks, etc. Just infantry based fighting with crisp game play, dedicated servers, eSports, and modding support.
If you would like to see this type of game on Steam, you can "greenlight" Rekoil here.
