Yeah, no day cycle is very harmful for a lot of very basic RP. Night creatures -- and I'm not even talking vampires here I mean thieves and scoundrels -- are going sorely unrepresented. The city of Baldur's Gate is risking to be extremely unatmospheric.
Absolutely. One of my favourite things about BG2 were the sounds at night while walking around the Slums or Docks area, it created such a potent atmosphere and one which mostly suggested inherent danger. It will be a farce if we can only experience the city of Baldurs Gate in permanent sunlight.
