Imagic

Imagic was a short-lived American video game developer and publisher that created games initially for the Atari 2600 and later for other consoles. Founded in 1981 by Atari and Mattel Intellivision expatriates, its best-selling titles were Atlantis, Cosmic Ark, and Demon Attack. Imagic also released games for the Mattel Intellivision, ColecoVision, Texas Instruments TI-99/4A, IBM PCjr, and Magnavox Odyssey². Their Odyssey² ports of Demon Attack and Atlantis were the only third party releases for that system in America. The company never recovered from the North American video game crash of 1983 and was liquidated in 1986.
