Since I'm quite familliar with the topic, the writer, and polish reality, I feel I should make a contribution to the discussion.
Dragon Wench, great point. Poland is definetely NOT a good place to be a woman, especially fantasy-liking, and Sapkowski is partly responsible for this. Since his books were the almost-only fantasy books ever to be even talked about by litterature critics, everyone sees him as a model, an ideal to be imitated. And he is the one responsible for clenching tight together fantasy and sexual violence, rape, beating women and abusing them. He, and his fans, claim that "this is real writing, not lying and sugary-dreaming". But none of them remember that people are influenced by reading about such behaviour. There are different ways to describe, for example, sexual activities. They can be either "lovemaking", or F-ing. Sexual violence can be described like an atrocious crime, or like a "normal" passtime for any armed male, like "oh, this is the way of the world, my dear...". Sapkowski does the latter, and leaves it for the readers to judge, which is one of the worst things you can do. Because people are not intelligent, sensitive and considerate. They tend to get fascinated by having an opportunity to touch such a taboo, and it stimulates their imagination, when not explictly condemned. Almost always.
That is why, on two out of three fantasy-conventions I have been taking part in, there were people who
demanded that rape be included as an activity to perform, if you want to. They did not find that idea at Tolkien's. IMO, such people should be placed under police custody, because they are likely to take their fantasies elsewhere, and hurt someone.
The books in themselves could be very well described "a teenager's wet-dream", even if the author is forty. We all know that inside every adult man there's a teenager waiting to get out
Just look at the main character - a "better man", a master swordsman, philosopher, scientist (genetics, anyone?), alchemist, mighty strong, tough, intelligent, wise, attractive to all (and I mean all, in no book you will find a woman that shall not wet her pants on seeing him) women, fearsome to all men, capable of making specific, mysterious magic, always winning, then drinking hectoliters of alcohol, then having sex with legions of women... uff. And that's only the start of it. No wonder the books are so popular, and no wonder the game imitates that. But should it really? The main reason for being so "faithful" to Sapkowski's, let's face it, medium - quality writing, was to make money on his fans. And this "faithfulness" is the main reason why it looks like a teenager's wet-dream.
That said, the game has its good points, with different combat styles, potions you can make, and signs you can cast. I suggest that anyone out there who does not like the sex part just say "no, thanks", anyone who does not like cursing click trough the conversation, or turn the volume down, and enjoy other features. And if you do, take pride from not being a D&D high shool nerd
