Lords of the Realm 3

Description:  The third installment in the Lords of the Realm series is a medieval real time strategy game. You are one of the medieval kings of Europe, and are trying to conquer all your rivals.  In the management part of the game, the map is divided in to several regions, and each region in turn is divided into several parcels. One of these parcels is your castle, from which you govern the surrounding parcels. To each parcel you can assign one of your vassals, a knight, a cleric, a serf or a burger. Each vassal will provide you with a different bonus. But this is only the part you prepare for the real battles. When one of your armies face an enemy, you have the chance to command the armies yourself or let your knight do his job. Whatever you choose, the game time continues to advance, which makes your attention a very important commodity.  The battle, be it a skirmish or a castle siege, lets you command a wide verity of troops, from horseman to siege engines, while letting you experience the battle field in all its glory. The game uses classical real-time controls, so you will get used to commanding your armies in no time.   (From Mobygames description)
