Imagine you in online game**(PvP)** and the time change from Day to Night . It would be great to add such as this feature to the gameplay system.
Love it, should definutely be an add on feature or option in the graphics settings.
Hows this?: Seasons
why stop there?
less visibility in the night (possibly torches which increase vision but can be seen from further away)
rain (slower troops, especially cavalry, torches and ranged combat mor limited)
snow (slightly slower troops and increased visibility (because everything stands out from snow)
