The Liberated Pixel Cup competition has been backed by the Creative Commons, Free Software Foundation, Mozilla, and OpenGameArt. By today's standards, the games it yielded aren't visually impressive by any means. The Liberated Pixel Cup competition was limited to using 16-bit RPG-inspired style graphics with 32x32 pixel tiles. They say this limitation was imposed in order to "build something easy to collaborate upon on which a wide variety of games can be built."
Last summer, shared were reviews of the Liberated Pixel Cup games. LPC has now announced the game winners.
The overall grand prize winner of the Liberated Pixel Cup is the Lurking Patrol Comrades MMORPG. The winner of the HTML5 grand prize was Big Island while other winners were Castle Defense and Laurelia's Polymorphable Citizens.
