Wizardry Empire (Japanese: ウィザードリィ エンパイア, Uiza-dorii Enpaia), published in 1999 by Starfish, for the Nintendo Gameboy Colour portable video game system. A sequel Wizardry Empire ~Staff of Resurrection~ using mostly the same gameplay-system, came out in 2000.
Empire's engine is most closely based on Wizardry Gaiden: Suffering of the Queen and Wizardry Gaiden II: Curse of the Ancient Emperor, but like Wizardry Gaiden III: Scripture of the Dark and Wizardry Gaiden IV: Throb of the Demon's Heart it started incorporating elements of Wizardry VI: Bane of the Cosmic Forge, while retaining the core gameplay derived from Wizardry V: Heart of the Maelstrom. It also adds a significant amount of additions of it's own.
