Ambient creatures/tribes/cities on planets? (where logical)

If you feel the need to believe that in order to keep enjoying this great game then all the power to ya. But me being a literal, logically minded individual and a major in ecology and having an obsession with natural sciences and ecology since I was old enough to read a book I not only find it redicules but IMPOSSIBLE to think, or even pretend to think that those forests are just... Trees..
Void of every other lifeforms but foliage.

I mean where is the biological base, where is the top?? Fauna needs foliage, and foliage needs fauna.
But I'm not looking for an arguement, just an opinion

But I like a game with more layers to it and though I don't believe that it should have a significant effect to gameplay I would appreciate seeing larger wildlife roaming through the forests and planescapes of the forested planets just before I crashed a moon into it because an enemy has a base located on a small region of it. Lol

Want to fight aleins in a strategy game, pre order civilaztion beyond earth.

I could..
However there is one problem..
Civ beyond earth is a TOTALLY different kind of strategy game.

And I guess by what you are saying you think trampling ants is considered fighting them. Assuming you read my entire post of course
