"ActionTrip: What are the main things you felt were missing in Oblivion? Are we going to see any of that in the expansion pack?

Mark Nelson: Because of the sheer scope of Oblivion, and the number of NPCs involved, I never felt like we had the chance to really develop enough of them, to give them all stories and a real place in the world. With the Shivering Isles, we are working with a much smaller group, and it's really allowed us to develop them more fully. I think it makes the world a more interesting and believable place.

ActionTrip: Oblivion's striking visuals, unfortunately, are sometimes simply too much for modest rigs. Is your team working on certain technical improvements to make sure the original is even more enjoyable?

Mark Nelson: There's always an ongoing process of bug-fixing and optimization to the game, but we're not going to attempt to change the core game to run on slower systems."
