Heroes of Might and Magic 3: The Shadow of Death is an expansion pack that includes the original game (Heroes of Might and Magic 3: Restoration of Erathia), does not include the Armageddon's Blade expansion, but includes most of its features such as the new neutral creatures. Heroes of Might and Magic III: Complete is the best bundle as it includes the original and both expansions. One thing missing in Heroes III: Complete are some expansion campaign video clips.
