Anepsosis, an open-source 3D MMORPG, has recentlly decided to release all of their game art (which includes texts, pictures, sketches, drawings, 3D art, and sounds) under a CC BY-SA license. This allows all the content created by the Anepsosis community, not just the final game, to remain open and free, adding additional functionality to the already open-source project (Anepsosis is being released under the GNU GPL Version 2).
