King's Quest 8 (Mask of Eternity) is a terrible game. King's Quest is an adventure game series. It is known for hand-drawn 2D character sprites moving over hand-drawn 2D backgrounds, collecting items and solving inventory puzzles.
This entry in the series tried to "modernize" it by adding in 3D graphics and RPG-like combat elements, which completely went against everything the series stood for. The 3D graphics were around N64 quality and aged very poorly.
It's considered to be a game that killed off the whole Adventure game genre.
