When the biomes are in balance, and native animals returned to their ideal habitats, it's time to recycle everything, leaving only a self-sustaining ecosystem behind. And while I'm able to put down the machinery that raises the humidity to bring back rainstorms (and salmon, and mosses), the rain by itself does a better job of cleaning up than I did. There's a moment when I start a controlled burn when I expect it to only take the flowers I targeted - only for the fire to rip through to the natural boundaries of cliffsides and water edges.

There's something tactile and immediately satisfying about converting one of your irrigators into a hydroponium and seeing it ripple out into wetlands, or placing a beehive and hearing the brush of flower and scrubland pop up.Īt the same time, it's made clear that you aren't freely zoning the land like an architect, or even a gardener.

With a foundation set, the next task is to restore local biomes, of wetland, forest and fynbos.

What you give to the land and what you take from it renew each other, and so tasked with restoring a barren quarry to a thriving ecosystem, you start small. The first level of Terra Nil feels like perfection. The reverse city builder is trickier than it appears, but utterly committed to its environmental vision, taking the genre - and every level - to new places.
