Icewind Dale had a lot of dialogue, but that dialogue
Yeah, no. Betting odds are 100% you never played Icewind Dale when it was released.
It obtained roughly 70-80% scores at the time because (drumroll):
it was a pure hack-fest without much character personalization or narrative structure.
I, at the least, am old enough to have played it at launch - you, I think, probably haven't even played it.
