Ecolibrium is an eco-system simulator where you’ll have to try to create and maintain a harmonious ecosystem. You’ll do this be creating animals, plants and artifacts. If things aren’t going well you can either manually feed the animals or exile them to the wilderness for other players to pick up through near. Ecolibrium also includes player-to-player auctions, online challenges and global leaderboards.
Includes Trophy support
Isn't this always free just like Cliff Diving?
