Platinum Games, developers of games such as Bayonetta, Madworld, Metal Gear Rising and Wonderful 101 are going the “licensed” route this time. I’m pretty sure they will find a way to overcome the “licensed game” curse.
The trailer does not tell show any game play unless PT is going for graphics that look similar to the show, which would be neat.
The game will take place between Book 2: Spirits and Book 3: Change (Which will begin airing tomorrow (as of this writing).
Korra will have access to all four elements (Water, Earth, Fire and Air) and use special moves based on said elements.
There will be two versions of the game. The big console version will be a beat-em up style game ala Bayonetta and Madworld. The handheld version will be a turn-based strategy game.
The Legend of Korra video game will be released as a downloadable title for PS3, PS4, XBOX 360, 720 and PC this Fall. Not sure the 3DS version will also come out this Fall.
