Archon: The Light and the Dark is a 1983 video game developed by Free Fall Associates and published by Electronic Arts. The concept is similar to chess, but with real-time fights between pieces to decide the winner. It was originally developed for Atari 8-bit, then ported to the Apple II, Commodore 64, ZX Spectrum, Amiga, Macintosh, and other platforms.
It was considered one of the best games available for Atari computers, but it was also a big hit on the Commodore 64 and later the Amiga.
