I'll take it
More details are coming out of the woodwork for Hyrule Warriors Legends, which is set to arrive in January in Japan, and March elsewhere. Evidently there will be a "My Fairy" system for Adventure Mode, which should give players a little something more to do than grind out objectives and maps. Now, you can raise a fairy character, feed it food, and have them contribute during combat with magic.
Additionally, a ton of new costumes have been confirmed, as well as a new Adventure Mode map called "The Great Sea." Wow, this is one hell of an expansion.
