Strategy/managerial game set in the medieval England, much like Defender of the Crown. You start out as a young knight in control of a small fiefdom and perform the usual managerial decisions to develop your economy, raise an army and expand your territory. RPG and arcade gameplay are also thrown into the mix as you have to develop your character as a knight, going to melee and joust tournaments (actually arcade sequences) to gain experience. They also have other uses such as affecting your popularity and offering you the chance to expand your fiefdom by allowing you to courtship noble ladies.
The game is mostly played from an isometric view, except for some specific screens, and uses svga graphics. When does the game end? you actually have two choices: when you grow tired of obeying William the Conqueror's orders and march to London to rip his crown off, or when you go the hero route, and hunt down the enormeous dragon that has been scorching the lands for years.
Conqueror: A.D. 1086 had one major flaw. (Whether it was intentional or just a balance issue is anyone's guess.) One could literally traipse around England conquering all in your path with a huge, lumbering army without having to worry about securing your castles. Quite simply, if an enemy army came marching into one of your acquired territories, and so long as you had left behind a single knight to guard it from being overrun, the game would take you to its First-Person combat mode. As long as you were good enough to win in this mode, one could repel even the largest of armies from invading your lands.
