It really surprises me that this game is about 10 years old, but there is no weather system. It would be really cool is there is a dynamic weather system with rain, wind, cloudy days, etc.
I just want a UI App that just says: WEATHER sunny partly cloudy cloudy rain heavy rain and thunder Just click the weather you want, and BADABAM, rain or any other weather for realism purposes. It would be so good! And easy as well. Rain would probably of course make the roads wet.
I guess the reason why we don't have it yet is because the default rain in the game engine looks super ugly and improving it is low on the priority list and they can't release a weather system when it looks like this
\ This. Weather isn't all that important to the team right now, and if it's being done it's definitely not high-prio.
Weather is more than just some visual effects. To have proper rain it need make any surface more slippery.
