Imagic

Imagic was an American video game developer and publisher that created games initially for the Atari 2600. Founded in 1981 by corporate alumni of Atari, Inc. and Mattel, its best-selling titles were Atlantis, Cosmic Ark, and Demon Attack. Imagic also released games for Intellivision, ColecoVision, Atari 8-bit computers, TI-99/4A, IBM PCjr, VIC-20, Commodore 64, TRS-80 Color Computer, 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 video game crash of 1983 and was liquidated in 1986.
