If you ever played spore chances are you felt something was missing from the experience. The game was pretty fun but it was very narrow when it came to evolution and all the creature stuff. Well this game is a simulation on evolution. From what I've seen its pretty cool. Well things that I should mention is that the game is in Alpha and is under heavy development. It is a free download. It is mostly simulation as of now and many features are fairly rough. I am not a representative for the game. so don't ask me any questions about the development I just liked it for some reason. I originally heard about it on the KSP forums. I'm sharing this because I think it has potential.
Here goes some links.
