Terra Nil (Devolver Digital)
"Terra Nil is a game about transforming a barren, lifeless landscape into a thriving, vibrant ecosystem. Turn dead soil into fertile grassland, clean polluted oceans, plant sprawling forests, and create the ideal habitat for animals to call home. Then recycle your buildings and leave no trace that you were there. Reclaim the wasteland." - Author's description
