yeah, this problem has been discussed on the site elsewhere too though, repro'ing has become so easy that you start seeing shady people trying to scam people who don't know any better. Honestly, I'd never even heard of Hagane, so I'm kinda surprised someone went after that sector of collectors as well. Earthbound on the otherhand is very well known, so I'm sure you've got plenty of joe blows buying the game to enjoy that are unwittingly playing a fake
