You're just replacing the word "censorship" with a euphemism because you find the original content morally offensive.
But I'd wager that many of the people saying they'll pass now, and this includes myself, aren't upset about the lack of anime titties. There's no shortage of tits on mobile games or ... why even start? They're everywhere.
It's the fact that a release has been watered down and changed and is no longer the originally released version. When Zelda: OOT was changed to remove the Islamic chanting, it lost some of its integrity. When they removed skeletons and skulls from Dota 2 to appeal to Chinese players, it lost some of its integrity. I just realized I'm starting to sound like Randy Marsh here...
I'm part of #JapanExpats and one of the jobs I had recently was helping a British director sell copies of his film which starred a Japanese teen actress. I went to one of her idol group's performances and I was ... revolted, to put it straight. DVDs of girls in their early teens, wearing swimsuits and school uniforms were being traded amongst adults (some women, included). Fans would pay by the minute to talk to these "idols" and get pictures with them. It's an odd scene.
I haven't played TMS (I want to), but from reading the comments here it almost sounds to me like part of the intention of the game was to expose the skeezy nature of the idol business. I haven't played it yet so I can't say for sure, but if I do I want to see the warts. Even if all it does is gross me out, I don't want a sanitized version of the game. Vagina bones or that already plenty conservative wedding dress would never have even been a blip on my radar, but a publisher attempting to "protect" me from it definitely would.
It doesn't really bother me that people here misconstrue this type of opinion as just "creepy guys wanting to see naked children" because I know where I'm coming from, and it's not from there. This place is also anonymous, so I don't have to deal with these misunderstandings in real life. Hopefully this helps elucidate things for you guys making reductive drive by posts.
