yes but the "old world/lands" in gothic 2 are mostly filler and if you have played the original gothic then its kind of a letdown to visit the old areas that were so vibrant in the first game with a mere fraction of its content. the old camp is still one of my all time favourite "cities" in any game.
Revisiting the Valley of Mines in Gothic 2 was one of my favorite parts of the game, and it certainly didn't seem like filler to me. I liked how the changes to that area reflected the recent events in that region. I would have been disappointed if they had just left it exactly the same as it was in Gothic.
