Ecosystem isn't just a video game version of the laws of ecology with pre-made fish models. The simulation actually determines the creatures in the game: their bodies, how they swim, and how they think and behave. All the creatures in the trailer evolved on their own in the game; none were hand-edited!
Really the most Species ALRE-like evolution sim I've seen yet, looks promising.
