Dynamix
Dynamix was an American video game developer founded in Eugene, Oregon in 1984 by Jeff Tunnell and Damon Slye. In 1990 Dynamix was purchased by Sierra. After Sierra's parent company was acquired by Vivendi Universal in 2000, they decided to restructure various companies they had acquired in the deal. Dynamix was closed on August 14, 2001 as part of this restructuring.
They developed several games with their DGDS engine (Quarky & Quaysoo's Turbo Science, Heart of China, The Adventures of Willy Beamish, and Rise of the Dragon), as well as Space Quest V.
