There is no real use in arguing either way for this hot topic. I'm disappointed the OP even brought it up and even more disappointed it became such a hot topic as expected. This isn't an issue that can be debated, most of us don't even know what we're talking about.
Humans are not born thinking nudity is wrong. Society instills that into them, but even then a grown adult can't explain to a child why it's wrong to be nude, why it's indecent to be naked even though every other living being is so. We're even born that way. Yet logic doesn't prevail and probably never will. It's something too strongly ingrained to the point where logic fights the social powerhouse, a battle that will never end, at least not for quite some time.
Thus in the end I would like to bring up a quick point: both sides are wrong in this case. Conflicts arise when one person steps out of their "bubble" to muddle in another person's "bubble". The best advice really is to "mind your own business". You have a life and should be busy enough with it that you shouldn't need to dictate another's. What do I mean about this? Well, it really doesn't matter whether or not any of us think nudity is right or wrong or if this is even considered nudity. The gentlemen and ladies who made Demigod are the ones who made this choice, and it was their right to do so. Hopefully none of us are arrogant enough to believe we have any right to decide what they do, even if we are the customers. In they end they offer a product; the only real choices you have are in buying it or not.
Thus, the argument is moot. Right or wrong, it was Stardocks and GPG's choice to make. They made it, now your choice is down to what your reaction will be.
To the gentlemen who is the OP - I'm sorry, you're not going to be ignoring Queen of Thorns. My humble suggestion to you is to move on to a different game. You really have no right to demand anything at all, your only power lays in buying the game or not. If you don't like nudity and consider QoT that, then moving on is probably a good idea. Much like an rts gamer who thinks Demigod is a watered down RTS and moves on, you'll have people who disagree with your thoughts but once again it's yours to make and react on.
