Mana o’ mana
Final Fantasy Adventure (Mystic Quest in Europe,Seiken Densetsu: Final Fantasy Gaiden in Japan) turned into the Mana series with Secret of Mana. Unfortunately, its entries have been relegated to Japan-exclusive cell phone games since 2007.
The most recent one, free-to-play Rise of Mana, is getting Final Fantasy Adventure‘s boss added in. At the end of the video announcing this is word of a new Final Fantasy Adventure project. A remake of the original, or a new Mana? Temper expectations, of course.
