Seems like a good upgrade for the day/night cycle and weather from beeing cosmetic in CS1 to something maybe a bit more realistic.
Hopefully the day/night cycles can be toggled on/off. I don’t know why I dislike building during the night in CS1, but I do.
I hope there’s at least some extra light added when you have any build tools active. I like how my cities look at night, but agree that building at night is a bit annoying.
I find it highly dependent on the map theme in CS1, on some maps it is the worst, on others it is not that bad. But yes, an option for it would be good. Although I suspect mods for the it will appear quite soon after release on PC.
I just hope the visual effects are a little more adjustable. I hate fog in cs1 I cant see a damn thing.
