Fantasy Zone (Sunsoft)

Two different versions were released for the Famicom/NES. The Japanese version was released in 1987, developed and published by Sunsoft. The American unlicensed version was released in 1989, developed and published by Tengen.

In the space year 1422, the Fantasy Zone was cast in panic at the collapse of the interplanetary monetary system. The Space Guild brings to light the plans of the planet Menon, whose forces are stealing the other planets' currencies to fund a huge fortress in the Fantasy Zone. Opa-Opa is sent to stop the invading army and discover who is behind it. In the end, it turns out that the leader was none other than Opa-Opa's long lost father, a revelation that leaves Opa-Opa with mixed emotions.
