Might and Magic VIII: Day of the Destroyer is a role-playing video game in the science fantasy genre developed for Microsoft Windows by New World Computing and released in 2000 by The 3DO Company.

The experience, spells, levelling and skill system present in both previous Might and Magic titles is retained, with only minor updates.

Aside from human Knights, Clerics and Necromancers, the available classes are Minotaurs, Vampires, Dark Elves, Trolls and Dragons, each of whom possesses traits unique to their particular race.

As with its two predecessors, the game world is divided into fourteen "regions", including five elemental planes, each of which contains a varying mix of explorable towns, dungeons and wildernesses.

[7] During the millennium since, the original colonists of that world (which include fantasy races as well as humans) built their own society and culture from the ruins, the stories of the Ancients and the Kreegan having long since passed into legend.

In each case they cause an environmental disaster: a volcano in the Dagger Wound Island chain erupts and the tremors destroy the bridges that link the Lizardman-inhabited islands, the Minotaur undercity in Ravage Roaming is flooded, the trees in a large area of the Murmurwoods are uprooted by the winds, and much of the Troll settlement in Ironsand is destroyed by an explosion of fire.

IGN praised the game's rendered cutscenes, storyline, setting and background along with its overall consistency and expansion on the Might and Magic universe, noting these as particularly strong points, but was disappointed with in-game graphics and the reused engine's low modern capabilities, citing these as pitiful compared to other, more modern RPGs.

[18] This was echoed by GameSpot's reviewer, who, though intrigued by the series' addictive charm, was displeased with Might and Magic VIII's tedious interface and pointed out the imbalance of the Dragon character class.

"[19] In Japan, the game was ported by Imagineer for the PlayStation 2 under the title Might and Magic: Day of the Destroyer (マイト アンド マジック 〜デイ･オブ･ザ･デストロイヤー〜, Maito ando Majikku 〜Dei obu za Desutoroiyā〜).

Before this port, the last game in the main series to appear on a console was Might and Magic III: Isles of Terra, almost ten years previously.
