I fully agree...
I really hope that the sound quality in Oblivion will be good, one thing I really didn't like about Morrowind was how I didn't get much
scared walking in a tomb or something. But as I've played DOOM3 in total darkness I really see how much sounds play a role in a game, so I really hope that Oblivion will have really good and scary sounds if I for example was sneaking around in a dungeon full of skeletons etc.
And if the sound enhancement for Morrowind was good then I really hope they will work further on that in OB...
