I really love old tales, despite the fact that their original stories are very cruel (and it's not what I like), but the plot in them is much more mature and complex. And, like a huge number of other players, I really love the Witcher, especially how world developed in the third part.
Of course, I can not but try to combine these two things, such as the story of a girl whose grandmother lives in a house away from the town, and a wonderful huge world full of monsters, witchers and great landscapes.
