Terra Nil is a reverse city builder about ecosystem reconstruction. Turn a barren wasteland into an ecological paradise complete with different flora and fauna. Then clean up, leaving the environment pristine. Subverting the builder genre, Terra Nil is about the restoration of a ravaged environment

Saw this discussion on r/ecology regarding an ecology based game! This one is beautiful and fun and is on steam (pc) and Netflix(?)!
