No Export for You: The Japanese series instead replaces Wizardry IV with a different and more traditional entry in the series, Throb of the Demon Heart.
They still included it in their "New Age of Llylgamyn" set, which included the original and Japanese remake; as well as Bane of the Cosmic Forge. We don't have an english version of the Japanese remake though.
Port Overdosed: The original 1981 game was ported to practically every computer then in existence and several after. Additionally, its unexpected popularity in Japan led to several console ports as well.
Sadly it never made it to any of the Atari computers (8 or 16-bit).
