I would like to see a living nature, which depends on the different animals and the player. For example in one map there are wolfand deers (I hope, that's the correct word). The wolfes hunts the deers, because the need them to live and ensures this way, that there are not to much of it. If the player exterminates the wolfes, he maybe cold have the problem, that there are later to much deers. And if he exterminates the deers, than would be his problem, that there are more wolfes who attacks the humans. And of course, not only regenerating fauna please. I have the same problem like the others with the forests. It's really ugly if there is no forest anymore. I suggest, that there are areas where trees aren't able to grow. For example every building has an aera where new trees can't grow, the streets and all places whith much movement. And different seasons which influences the animal's behavior. For example a lot of deers dies in the winter and wolfes attacks humans. This is only an example how it could be. It could be like in Gothic/Gothic 2, where are many different animals which have their own behavior and "food".
