Evolution: A Creature Simulator

Evolution: A Creature Simulator is a simulation game released for the Xbox One X and for the PS4 in late 2017. Rather than focusing on creatures, it looks at fish in a 2D style. However, the fish aren't in the same way they are in real life. They have randomly generated looks, AI, and other things. In the beginning of a simulation, a meteor falls into the ocean and splits 50 fish into the sea in a set pattern. Herbivores are set into the bottom left corner, carnivores are set into the top corner, and omnivores in the top right corner. The map is over 50k cubits large.

The game has received very high ratings, infact it is tied for second on Metacritic, globally. Most critics gave it a 10, and some gave it a 9.75.

AI
The most important aspect of Evolution is the AI of Evolution. Fish may choose to be carnivorous, herbivorous, or omnivorous based on how they act. There are over 2000 traits for each fish, with over 1000 judging if the creature is herbivorous, carnivorous, or omnivorous.

This is an example. A herbivorous fish with the "Intelligent" trait spots traces of dead meat, indicating that a predator was once there. The herbivorous fish leaves, and a predator enters later to find nothing there.

If a fish reproduces, it inherits some traits from one fish, and some traits from the other.
