I'd rather they didn't have nudity in books most of the time.
I work at a gaming store. We have a fairly strict policy that if there's nudity in a product, we bag it and put a mature label on it. That means that people can't casually leaf through it, which is how we sell a good chunk of our gaming products. It's inconvenient for us, and the customer.
Further, I just don't think nudity adds anything significant. I mean, that's hardly the purpose of a gaming book. If I want to look at that sort of thing, I'm not going to head for my gaming bookshelf. I have the Internet.
