What people want is that we have the same degree of mechanics and immersion as ....uh... Baldur's Gate.
Not less.
Again, what does a day/night cycle mean to you?
In Baldur's Gate, what was it except cosmetic? The dimmer switch is really all it would take for you to feel "immersed"? If that's really all it would take, then both I and Larian both seem to struggle with understanding this. A cosmetic day/night cycle is not at all hard to implement in a game, but I guess we just kind of struggle with understanding the point.
I really don't care for a cosmetic day/night cycle. If it's implemented, it should matter.
