I think my only complaint really w/ Divine Divinity was the English voice-acting (audio) was more on and off than a light switch.
EDIT:
I think the two main selling points for me were the freedom to pretty much go where I liked when I liked and the system, which allowed me to develop my character in any way I wanted with scant regard for what class s/he technically was.
Yeah, I really dug the class-less system, as well. My character turned out, by the end, to pretty much be a fighter/thief that also knew a healing spell.
