Claiming that the only thing a day/night cycle added was "getting tired after a long travel and waiting for shops to open" *IS* dismissive and condescending. Not to mention oblivious to reality.
I would request that you re-read my post.
I never claimed it was the only thing that the Day/Night cycle added.
I supplied you with the reasons BioWare gave for getting rid of it.
The last installment of the Baldur's Gate Series did not have a Day/Night cycle because the developers of the game decided the feature did not positively effect gameplay.
You may not agree with that decision but that is how the Baldur's Gate series has evolved.
