The post I replied to, is deleted. Iirc it claimed something along the lines of those games being pornography in disguise. Which of course provokes a headshake and a groan... ;-)
But there were times and places and still are places where anything that might be called porn or has to do with sexual things would have to be disguised.
I believe there are places in the US where this applies to sex toys in this day and age. You can't sell those, but you could sell a personal massaging device. Crazy things like that.
