Only the dlc section caused my game to freeze, not once but twice. I got this for nothing bundled on sale with the trilogy but I would not be happy paying 15-20 for this back in the day. The first half is hold w until you have to leave to make a potion, you go back to the main game area to collect herbs and liver stuff. Then you just fast travel back and finally have new content in a over-extended boss fight. Basically, it just adds a 1 hour side mission with reused content.
