Why is it that everytime weather is mentioned, its always mentioned how "rain would be too dangerous". Why not just add weather for a visual effect. Fog and rain could be purely cosmetic and wouldnt actually have to be a game mechanic, moreso an addition to the atmosphere the game already has

Each raindrop would be the size of the player you would instant die on impact. It would be like a car dropping ontop of you.

With that said I do support weather there could be many options that can actually work like

1. Sand Storm

2. Fog

3. Heavy Wind

4. Toxic Gas Storm ( Pollution from nearby factory )

5. Deep Freeze

6. Sprinkler Mister = Rain
