Family Computer

Fushigi no Umi no Nadia (translated: Nadia of the Mysterious Seas) was released in 1991 by Toho for the Famicom console, based on the characters from the NHK animated TV series of the same name.

The player controls a cast of characters in a simple-looking battle strategy game. Battles are carried out through an RPG-style turn-based system.

This version of the game was poorly received due to its lack of originality and flawed gameplay.

Sega Mega Drive

This version was developed and published by Namco.^[1][2] While it is viewed from a top-down perspective, it is similar to a point-and-click adventure game. The player must talk to people and collect items to solve puzzles and advance through the game, but there are no combat elements to the game. There is a password feature that allows the player to resume from the beginning of each chapter. This version was released on March 19, 1991.

The plot of the game mostly follows the plotline of the original, but it diverges from the storyline in many ways. The introductions of Marie, Gargoyle, Emperor Neo, and the climactic moments, for instance, are drastically different from the show.
