Well the game world looked awesome. Much, much better than Oblivion back then. It had this kind of Gothic(game)-feeling, because everything was hand placed and didn't looked like simple copy&paste. But yeah, as far as I can remember, the visuals were the only thing I really liked. Oh, and I think the voice acting was really well done... just doesn't help if the writing is bad.
That said, maybe they improved for the new mod. No idea, haven't tried it and won't for a while longer.
