Here is some interesting news, as, Square Enix has filed a trademark for “Collection of Mana” in Japan. This could be a possible name for the localization of Seiken Densetsu Collection, but the trademark in Japan complicates matters.
Seiken Densetsu Collection originally launched in Japan back in June 2017. The package includes the first three games in the Mana series – Final Fantasy Adventure (Seiken Densetsu: Final Fantasy Gaiden), Secret of Mana (Seiken Densetsu 2), and Seiken Densetsu 3.
Do you think the collection is being localized?
