After reading about a volcanic eruption, I wondered how feasible it would be to add elements to the game which would resemble natural disasters, or the risk thereof. I believe it should be subtle, like a mountain tile with a 'volcano' subtype, which could be represented by an increased fertility/food yield, but which might also erupt occasionally. This could cause a (temporary) decrease in fertility or even an increase for tiles further away (fertile ash dropping) Earthquakes, meteors, etc could form mountains, chasms or craters; making tiles impassable. Possibly creating a new natural wonder in the process (Grand Canyon, Mount Everest, Crater Lake etc.) Similarly, maybe there could be climate changes; creating more viable settling options in the late game, when snow turns to tundra or grassland, or rainforest into deserts. Again, I think this all should be very subtle, as to not completely shift the balance of the game. But I think it would make the game a bit more dynamic and create more interesting options througout the game. I'm curious what you guys think of this idea. Would it make the game more interesting? Is it technically possible in the game engine? Would you like to see more features like this?
