Fog of War sounds like a good idea, but I guess it depends on the types of camera maneuvering they will provide.
As far as capturing the BG magic, that's easy! Just reincarnate Narlen Darkwalk and his crazy Thieve's Cant, which provided some of the finest dialogs in the BG series. Renal Bloodscalp was also very well done, but in a different way.
Another BG thing that captured the sense of adventure was that most of the houses had somebody in or around them. That aspect got dropped when BioWare moved on to Neverwinter Nights. I like the feeling that there are other characters out there doing their own thing, regardless of what my player character is doing. "Rumar? RUMAR! You will come home with me this very instant!" ha ha!
