I have to admit, I wasn't incredibly interested in this at first, but this is by far one of the best Kingdom Heart compilations yet.
In addition to having an HD version of the previously 3DS-only Kingdom Hearts: Dream Drop Distance, it also contains a new playable campaign featuring Aqua (from Birth By Sleep) and a movie version of KINGDOM HEARTS χ [chi] Back Cover, which features the origins of five Keyblade masters from the past.
Take a look at the new trailer and let us know what you think!
EDIT: Apparently it launches on January 24, 2017 in the West.
