【オクトラ】スクエニ、「HD-2D」を商標登録

Square Enix has filed trademarks for “HD-2D” and “HD2D” in Europe, and FuRyu has filed a trademark for “Heroland” in both United States and Europe.

“HD-2D” is the term used by Square Enix to describe the graphical aesthetic of its July 2018-released Octopath Traveler.
With the term being trademarked, it is possible that the company plans to use “HD-2D” as a descriptor for future titles, Octopath Traveler or otherwise.
