LE Does Dungeons and Dragons materials fall under the Open License Agreem

[Daggdag]

I know that Wizards of the Coast has an Open License Agreement, allowing authors and game designers outside of their company to create and sell original materials for Dungeons and Dragons (though Wizards of the Coast claims partial ownership of all materials created for DND), but my question is, does this only deal with pencil and paper games, or does it deal with video games as well? Would it be ok to use DND materials for mods, or is it considered cvopyrighted materials? Edited April 28, 2012 by Daggdag
