Well, IWD has a amazing story. Is just not the typical "saving the world" stuff.
Is just a small frozen region of Faerus which always had very decentralized small cities/tribal societies and a evil tyrant wanna "unify" the region. Instead of "good vs evil", you have "chaos vs law". Each place that you visit have a unique lore behind it, the dungeons are gorgeous,
I don't like ludonarrative dissonance. Having wizards intellectuals on lore and a low int wiz possible in game makes no sense.
