Rain, snow, fog, and storms that aren't just pretty backdrops but actively change how you play the game.
Weather systems range from purely cosmetic visual effects to game-altering mechanics. In Breath of the Wild, rain makes surfaces unclimbable and lightning strikes metal equipment, forcing gear changes. In Metal Gear Solid V, sandstorms reduce enemy visibility but also affect your own targeting. Forza Horizon's dynamic weather changes road grip in real time. The most sophisticated weather systems cascade through multiple gameplay systems simultaneously: visibility, movement, combat effectiveness, NPC behavior, and resource availability all shift when a storm rolls in.
Example
Red Dead Redemption 2's weather affects everything. Cold temperatures drain health if Arthur isn't dressed properly. Snow slows horse movement. Rain muddies roads and affects wagon handling. NPCs seek shelter during storms. Fog reduces draw distance for hunting. It's one of the most systemically integrated weather implementations ever shipped.
Why it matters
Weather systems add a layer of environmental strategy that keeps gameplay fresh without requiring new content. They create emergent situations the designers never explicitly scripted and make game worlds feel alive and unpredictable. Dynamic weather is one of the cheapest ways to add replayability to an open world.
