Disciples II: Dark Prophecy

Disciples II is a fantasy strategy game set in a fictional kingdom called Nevandaar (also called "The Sacred Lands"). The story centers around four dominant races that are in an almost constant state of war. These four factions are the human empire, the dwarven mountain clans, the demonic legions of the damned, and the skeletal hordes of the undead. There are also a few other "neutral" races, such as the merfolk, the greenskins and the elves (the elves became a fully playable race with the Rise of the Elves expansion pack). The game is divided into three main parts: the construction of your people's capital, so you can research new warriors and spells and raise new armies (this requires careful resource management); the use of heroes (who lead small squads) to explore the environment, obtain resources and attack the enemy; and finally, the battles themselves.
