Might and Magic IV: Clouds of Xeen is the fourth installment in the Might and Magic series.
MMIV focuses on the events that had occurred after Might and Magic III. Trouble is stirring on the Nacelle world of Xeen. A mysterious villain by the name of Lord Xeen has claimed ownership of the land and is unleashing havoc throughout the Nacelle. A new band of adventurers must be formed to stop him and save the Land of Xeen.
MMIV uses a game engine based on that used by Might and Magic III: Isles of Terra, and the gameplay is almost identical. More emphasis is placed on cutscenes than in the earlier game, perhaps due to the availability of larger hard drives.
Might and Magic IV and V combine together to make "World of Xeen".
Might and Magic IV and V were some of the very first games to come out on CD. They are also the first games to come out where every character will 'speak' to you via sound that is recorded on the CDs. (It plays the CD back at specific tracks, seeking to the proper min:second of the track).
