In Terrarium, developers create herbivores, carnivores, or plants and then introduce them into a peer-to-peer, networked ecosystem for a survival-of-the-fittest type competition. The game provides both a competitive medium for testing your software development and strategy skills as well as a realistic evolutionary biology/artificial intelligence model for evaluating the role that various behaviors and traits can play in the fight for survival.
