I've been meaning to buy a One Piece but skipped because they just didn't look that interesting to me, however, I might give this one a try as it's on the Wii U and it's action/adventure genre with some open world elements.
By the way, Namco Bandai seems to have something against Xbox 360 because there hasn't been a single One Piece game for Xbox so I'm glad I'm not Xbox-only or I'd miss out on this.
