Robert J. RJ Mical (born 26 January 1956) is an American computer programmer and hardware designer who has primarily worked in video games. He is best known for creating the user interface, Intuition, for Commodore's Amiga personal computer (1985), contributing to the design of the Amiga hardware, and co-designing, with Dave Needle, the Atari Lynx color handheld (1989) and the 3DO Interactive Multiplayer (1993). He also worked on arcade games at Williams Electronics, was the chief architect of the Fathammer mobile game engine, and was at Sony Computer Entertainment from 2005 to 2011 as a senior manager on the PlayStation product line. In 2012 he was hired by Google. A 1995 article in Next Generation commented It's true that of the machines that Mical and Needle have created, only the Amiga has been a true global mass market hit ... But it's only fair to put forward the argument that this is down to the marketing of the machines rather than the quality of the product.
