Some natural disasters should randomly happen during the game. Here's a list of existing disasters or some ideas :
* Black death
* Erupting volcano
* Pollution (optional please
)
* Floods : randomly destroy some buildings, kill citizen, create disease and terraform some plains into swamps
* Drought : no food at all for a city, kill some citizens
* Prosperous year : 1 turn with +1food, +1gold per tile (not really a disaster)
* Earthquake : destroy some buildings
* Tornado : appears somewhere in deserts, seas, plains and move randomly on the map, destroying roads, farms, buildings (in cities), units and citizens (in cities) during 1, 2 or 3 turns.
Any other idea ?
