Do you even remember that project?
On a sudden urge, I picked up that dusty code and started hacking away at it. I've added a primitive war mechanic. If the 'open space' runs out in the world, any enemy tribes will start coming to you to try and get some instead. You can get game over if they kill all your people or steal all your land, which they will do without feeling guilty.
The wasteland just got harsher.
