I think the Witcher is probably the closest in look to the Drakensangs... there are some very similar places. Some of the pics of D2 look even more like The Witcher - there's one of a green-skinned woman who I'm sure was in two or three places in the Polish game. I'm just playing the first one now - lots of fun, in its own way
I think the style is very different.
Draksensang is like the Witcher re-imagined by a cilldren's writer
