Ni no Kuni: Wrath of the White Witch is probably one of the more unique PS3 games you're going to find out there. The newest trailer is pretty much a summary of the game itself, and if you haven't played it, well, it's a pretty nice primer. That said, if you do plan to play the game, the "Adventures of Oliver" video might be a little spoiler heavy.
As the title implies, it covers some of the events that boy-protagonist Oliver gets dragged into, following an apparent tragedy in his life. The ensuing adventure makes the young lad into a hero, unlocking in him a potential he never quite knew he had.
For anyone who doesn't quite mind light spoilers or already played, the trailer is worth watching. Game owners should also be happy to know that the release of Ni no Kuni's free Draggle Familiar DLC is looming nearer, expected to arrive February 12.
