I have yet to see any sudjustions for weather. I have thought about this for a long time. Now I see that many games have weather. For example it rains. Rain could partially blur your screen and make it harder to see at long distances. Possibly the same could happen with snow. Take minecraft for example. It has storms, rain, snow. It just adds a little extra realism.
If all of this gets shot down (which I believe it will), can we at least have clouds and a sun? For example when you look into the sun it can glare you eyes. I do not remember what game has this feature. I would mainly like clouds and a sun so that it makes sense when a map begins to darken.
