Fushigi no Umi no Nadia: Nadia and the Secret of Blue Water

This is the Sega Genesis game based on the animated television serial of the same name.
Nadia and Jean go on an adventure that very roughly follows the plot of the original.
This game is tagged for Beyond Oasis, so you'll need that game to play the mod.
You can use the passwords provided to cheat your way past as much of the game as you want.
But if I were you? I wouldn't bother. You'll miss most of the story that way, and that's the dessert of an adventure game.
The meat and bones is mostly running through mazes and getting items or triggering switches
The story's not half bad despite the major deviations from the original plot, and the end is intense, also pretty touching.
Still not as awesome as the original film I'm sure... I'm willing to bet if you've never seen it it won't matter.
Not for children: lots of death and blood especially toward the end. Violent scenes and themes.
Rated Teen if you ask me.
Overall, you can consider it the "movie version of the book" sort of deal, with mediocre gameplay and a decent story.

It is also not the NES version of the game. Go somewhere else for those.
