Valve has revealed 13 new games that have been approved for Steam via the Greenlight process, bringing the total to 50 since the project was launched in August. Also getting the greenlight were the first six non-gaming software titles.

"In just three months, the community has helped us identify 50 new titles for us to offer via Steam," said Alden Kroll of Valve. "With the help of Greenlight, the indie games market share of games sold on Steam has increased by 50 percent for a third consecutive year. That's a stat we are proud of, but one we also hope to increase as we learn more about Greenlight and continue to refine it in the new year."

• Primordia (Wadjeteye Games)
