Agreed about the spreading out.
But, to be honest, I think PB suck at making dungeons, and they never really made them well. Risen represents their best attempt yet, but they still basically recycle the same 3-4 puzzles in an environment with almost no variety. Not to mention VERY few kinds of enemies.
Look to the old Dungeon Master clones, or Ultima 9 - for how I prefer my dungeons to be designed
As for the rest of Risen, I think it was positively superb. No one does open world environments better - and I think the engine handled seamless loading magnificently.
I wouldn't mind more variety in terms of character development, but with the other improvements, it will be a minor issue.
