New Pokemon Games - The Loop


Just as in real-life cities of today, pollution becomes a problem to advanced cities in Civilization games. Certain buildings and nuclear weapons, or just excessive production, will make pollution. When pollution overflows in a city, it can create a pool of pollution, making one square of resources less productive until the mess is cleaned up by a Worker.

None under Despotism; under other governments, pollution builds up if the number of material resources being extracted is greater than the population number.
