Late to the party, but my 2 bits is if you have to mosaic it, don't bother.
I'll play something that doesn't need mosaics over something that has mosaics.
Which is to say, while I'm thankful for it as we get unmosaiced "hardcore" shots, I find it difficult to understand the jp mindset to use mosaics in the first place, when camera angles/clever obstructions that avoid the need altogether would (IMO) be preferable. Unless it's so that they CAN sell the unmosaiced version in other jurisdictions/under the table. (or people can modify them to make their own)
It has absolutely nothing to do with my views on censorship. I just find the whole mosaic thing extremely jarring/ugly. On a similar note, I won't buy something mosaicked with promise of a demosaic patch in 2 years. I'll wait until said demosaic patch is available before I buy it. (by which time I'll probably have forgotten about it.)
As such, I'm concerned with the "slippery slope". Once Jast releases one title with mosaics, it would presumably simply be a matter of time before other companies demand the same, and then there wouldn't be any without.
FWIW, I seem to remember the law against pornographic *depictions* of minors (as opposed to actual photographs, i.e. anime) is actually a relatively recent law in the U.S. (looked it up, 2003.) And from wikipedia there was a conviction (upheld in 2008) of somebody for possessing "obscene Japanese anime cartoons that graphically depicted prepubescent female children being forced to engage in genital-genital and oral-genital intercourse with adult males". That said, the law for *depictions* isn't as clear cut as photographs, and is based on obscenity or lacking any artistic/literary/etc. merit, which makes it a huge grey area.)
That said, I didn't realize there was anything illegal about scat or bestiality *depictions* in the U.S. and from a Quick google search only referenced it's illegality when depictions of minors are involved. I suppose it's possible it's illegal in other regions in question?
P.S. I find it peculiar that the reason they don't want to license non-mosaic versions until a later date or not at all is because reverse import of the international version hurts their domestic sales. I'm assuming I'm missing something, but that seems like that'd be a strong argument to simply make an international version themselves in the first place, instead of licensing it out.
