They probably think it was just some kind of trend that people decided to censor porn just for the heck of it and expected everyone to have moved on from it.In their defense, Jimmy, you don't want to risk ending up in a Japanese Jail. So unless there's a major movement to remove censorship, they'll have to do this in order to save their asses from a lawsuit then a direct way to jail due to guilty until proven innocent court philosophy. Also wtf are you yapping about this game's barely censored.
And even if it was exactly that, this game is a decade old. Were they expecting the developer to make a sudden come back just to make this game keep up with the uncensored trend?
