Understood, but I have to ask: what is immature about a sex scene where the participants are naked? I'm assuming you have had sex, yes? I am also assuming you have been naked whilst doing so..
I am puzzled as to why you think this is immature.
Ignoring the rather cheap shots you're throwing at me, I find sex scenes in general to be immature. Clothed or not. Yes sex is a common, everyday occurence. But it's also a private thing. It's very hard to pull off a scene like that without having a feeling of voyeurism.
Which is why I say stick to ftb and let the imagination take over
Sigh. The point is, as you well know, that if you are going to do it, do it properly, and if that means nipples are shown than bloody well show nipples. Or penises (penii?). Or someone's arse. Or whatever.
This is assuming it should be done. Why is there a compelling reason to show it at all?
I do not understand why people are struggling so much with the concept of nudity and how it can't be shown in a mature game. It's baffling - what do you think will happen? It's really bizarre.
When a TV show comes on that shows some nudity do you turn it off, or look away? Or is it only in games where you are not supposed to have it?
What do I think will happen? It'll drag down the maturity of the game. That it won't be done tastefully, or maturely, but simply for fanservice. Or shock value. In short, I don't trust the video game industry (or the entertainment industry in general) to handle nudity in a mature, grownup manner. Same with graphic violence really.
