Dragon 32/64 - Released - 1982
One of the world's first chess games designed for experts, Cyrus is also unfortunately one of the least known due to limited distribution. The IBM version can be played from a isometric 3-D perspective, or a traditional boring 2-D overhead view. There is a clock, which can be turned on or off. You can view analysis mode, examine game, or watch the computer play itself. The game has 16 difficulty levels!
