The ES games are non-linear as far as exploration goes. Morrowind actually presents some varied quest solving, even though most of the time this branching is just a different way to get to the same outcome. Daggerfall was almost completely linear in its quests. And boy were they horrible. Go to town X click on person Y who tells you to go to town Z where you have to find person A who'll tell you to go to dungeon B where you'll get item C to use to kill person D. Oh sweet mother of God...
