Slow work day, so lots of posting. Was thinking last night that a great addition to Civ, and to help break up the monotony of the landscape, would be more unique fauna (which would affect production).
These would be randomly generated one (or two/three closely found) tiles with unique animals (like komodo dragons, kangeroos, polar bears, tigers, lions, etc) these tiles would have minor production improvements (typically +1G or +1P) which would be destroyed if the tile was improved. So by the end of the game you are more likely to want to burn these things for the proper production bonuses (just like irl). But it would make the game nicer to look at (more variety) without debalancing it (the animals would not be luxuries or anything - though maybe you could later build (with Ecology) the nature reserve which does add science and happiness for every one of these animal types in the cities borders).
