Heroes of Might & Magic III: Restoration of Erathia was released in February 28, 1999 and is a dramatic evolution from both Heroes of Might & Magic I and Heroes of Might & Magic II. The basic gameplay remains the same in that you have to acquire gold and resources to build up your town(s) to produce enough creatures to give to your hero(es) so they can explore an adventure map and defeat wandering stacks, enemy heroes, and take over their castles. The differences, however, are what make Heroes of Might & Magic III interesting and fun.

Adventure

Heroes of Might & Magic III consists of seven campaigns in the lands of Erathia after King Gryphonheart of Erathia dies. Queen Catherine of Enroth is the daughter of King Gryphonheart and married to King Roland who was in Heroes of Might & Magic II. She returns to Erathia to handle the situation but learns on the boat trip that her father's death might not have been an accident. Because of the power void in Erathia, the surrounding countries decided to take some of Erathia for themselves. Queen Catherine will have to not only find out what happened to her father but keep the borders intact.
