With this expansion we’re unleashing the forces of nature to bring the world to life in a way that you’ve never seen before. We’ve always had Floodplains in the game, but I always found it disappointing that they were completely static. No longer! We’ve enlarged the floodable areas to include flat Grasslands and Plains tiles next to Rivers so these valleys can offer the potential of incredibly high yields. So you’ll still want to settle there — but now doing so comes with real risk.
