The beauty of the Gothics and Risen is that they are lovingly hand-crafted and every hill, ledge, cave put there with design and intent, every encounter, every piece of loot. It's not random and it shows, it makes a huge difference to the experience.
I've played sixty plus hours and only done a few of the main quests. Spent most of my time just wandering and exploring. I'm thinking Bethesda finally got it more right than wrong. Skyrim shows how much attention to detail they put into it. They may even have studied the Gothic games to learn what made them cult classics.
