FreeDoom, OpenQuartz Help Recreate Classic WADs

Toddd writes "Everybody knows that the Doom and Quake engines are opensourced. But the game data (such as graphics, sound, and maps) are not. Therefore, if you want to check out the quality of today's source ports like Doomsday for Doom or Tenebrae for Quake, you either need to download the shareware versions or buy the retail boxes. However, what is less well-known is the existence of projects like the recently updated Open Quartz, offering 'GPL-compatible content - including models, maps, sounds and textures - which are required for a fully GPL game using the GPL Quake source.' FreeDoom also does similarly for Doom." We recently covered a new release of Doomsday.
