Underrated Civ style 4X game Humankind is free to keep for a limited time

By and large, mankind has had a troubled history. We tend to run headlong into catastrophe, occasionally only surviving by the skin of our teeth. Correcting such flaws is an inherent fantasy of Humankind, a 4X RTS all about guiding people through several eras of evolution. It's an underrated project that went a bit under the radar for many, but now it's free for a limited time if you'd like to try.
