FASA Corporation created Traveller supplements, the first licensed Star Trek RPG, Shadowrun, BattleTech, Earthdawn, and other game products from 1980 to 2001. It exists now as an intellectual property holding company. FASA Games (2012-) is producing new games under license from FASA Corporation.
Were there significant edits between the hardcover (#6000) and the (second printing of the) softcover (#6001) editions of FASA's original Earthdawn from 1993, or did they just fix typos? :)
