Sacred Haven of Debauchery

But then, what's so bad about Morrowind if the role-playing aspect isn't any worse than in Icewind Dale?

I'm saying that the role-playing in Morrowind is better. Isn't it obvious?

But the world there, no matter how you look at it, is more developed and more extensive.

And that too, both games show small pieces of their worlds, but in Morrowind, that particular piece is revealed very, very well.
