"The new SDK allows MOD authors to create a much wider variety of games, such as isometric RPGs, fighting games, and real-time strategy games, in addition to new styles of action games," said Gabe Newell, managing director of Valve L.L.C. "Half-Life is currently generating over 350 million player-minutes per month on the Internet and is the most popular multiplayer game played online, and part of that success was made possible by the amazing content created by the MOD community. We have every intention of continuing our support for that community."
