The nudity doesn't offend me or make me uncomfortable, but if it makes someone else feel that way, why do you even care? Honestly its not affecting you in any way, so I fail to see why some of you people decided to make an argument out of that. It is merely a matter of preference, so everyone's opinion on the subject will obviously differ from person to person. I'll probably end up avoiding the nudity myself but still completing a romance (clearly one that doesn't require sex), because I just don't feel like watching the sex scene, its not that I'm uncomfortable or offended by it, just that I'm not interested in seeing it. That being said, since we've already established that some romances do not require sex, there shouldn't be any more problems, its a win-win. You want sex scenes, you got em, and if you don't, you got that option too.
Only thing I was wondering about were the desire demons, since they tend to be provocative and we have no details about nudity outside of romances. As long as its restricted to romances, then I'm perfectly okay with getting the game, especially since they do not need to be completed and sex is not required for all romance arcs. I'll probably have to wait for my question about the desire demons and other scenes outside of romances to be answered until after release, which is fine with me.
and violence isn't nearly as much of a concern as sex because violence is unavoidable in the real world, unless you live in a closet, it always exists and its everywhere. Sex is not something you see in public or in most stories, games, and movies. Violence is everywhere, it is not something that one can be sheltered from until a certain age. Although excessive violence can be questionable in some cases, its not as questionable as sex for younger players/viewers, because its not as difficult for them to understand/comprehend. You learn about violence at a much younger age than you learn about sex.
