A third ending is available in the combined games only. Both game's endings can be achieved, after either of which gameplay continues.

In the combined game, areas in both games become available that are impossible to access in the standalone games. In-game, this is visualised as either game being a 'side' of a flat, rectangular planetoid. This game and its successor, Might and Magic V: Darkside of Xeen can be combined together to make one large game, World of Xeen.

More emphasis is placed on cutscenes than in the earlier game, possibly due to the availability of larger hard drives. Might and Magic IV uses a game engine based on that used by Might and Magic III: Isles of Terra, and the gameplay is almost identical.
