I want to buy the game at the store, but can not find it, I have tried several ways but get the same result, I tried to get here http://us.playstation.com/games/one-piece-pirate-warriors-ps3.html , please help me. Thanks
It definitely is in the US Playstation Store. Use the search function, or look under PSN games, not full PS3 games. The game wasn't released at retail, and is downloadable only; so it is a PSN game.
