Didn't BG1 and BG2 have day night cycles and weather?? It even influenced events, quests, some spells etc...Remember that vampire only came out at night in the graveyard, the ghost boy, guards asking why your out so late, different random encounters, the fences of Athkatla who work for the Shadow Thieves, come out with their fancy magical goods, too .
Kind of a big deal not having this kind of BG stuff in. Instead we have cinematic dialogue with dicerolls...I guess.
