i have ice wind dale but ive got to the vale of shadows and opened the lot of it (even the locked door in the crypt at the top right of the map)
and killed the shadow (rather that the lesser shadow) now im bored and i unaquipt all my weapons and fight the yetis by hand
(u really have to know the game to know wat im on about!!)
Actually, that was a bit of a low point in the game, as far as I was concerned.
The endless combat with similar monsters in the area you just finished was about the weakest area in the game. (Though I thought the guy who is responsible for it all is a cool character with an interesting story--did you get that far?)
I think the combat gets more varied (and harder again) and the story gets better as you go along.
