In 1985, Psion Chess was released as a DOS game. It was developed by Psion, a British software company. The game is a chess simulator that allows the player to compete against a computer opponent. The player can choose from a variety of difficulty levels, and the game can be saved and resumed at any time.
Psion Chess was one of the first chess simulators to offer a variety of difficulty levels. It was also one of the first games to allow the player to save and resume at any time. The game was well-received by critics and was praised for its realistic graphics and sound.
Despite its positive reception, Psion Chess was not a commercial success. It sold less than 1000 copies and was discontinued shortly after its release. Nevertheless, the game is still fondly remembered by those who played it.
