Wow,
Yo-Kai Watch looks intense!
Honestly though, this looks pretty cool. But if they do release it in the west, they would most likely have to change a lot of the Japanese folklore demons seen in this trailer to be more "western" so that more people will want to buy it. Similar to what 4Kids did to a lot of anime back in the day (most notable being the Yu-Gi-Oh! animes, One Piece before Funamation took it, and the Sonic X anime). I know the game would sell more then, but we then loose a large amount of what the original has.
Then again, this is Sony, the same company that allowed a
J-Pop based rhythm game to be released overseas with the only differences being translated to other languages. So who knows?
