The Perfect General was a turn based strategy game for MS-DOS released around 1990. It was based on early 20th Century warfare, with armor, artillery and infantry.
The designers of the game came from a background of table top, non-electronic strategy gaming, but the game made it into electronic translation very well. By todays standards, however, the game is not very sophisticated.
Each game took place on a map, with two players, the attackers and defenders. Units, which the player could select with buy points, could fire, move and then fire again in that order. There was also seperate phases for artillery plotting. The goal of the game was not to destroy enemy units, but to occupy cities. Each city was worth a set amount of victory points, and at the end of a dozen or so turns, whoever had the most victory points would win, even if all their units had been destroyed.
Units had different ranges, chances of hitting a target, movement rates, and ability to sustain damage.
The game was hampered by a weak AI, but when I was a young child, I managed to play it for hours nonetheless.
