Gotten the simulation to actually update as well as adding important information about the world:

So in this God game you start at the dawn of history where hunter gatherer tribes of people roam the world. Life is unpredictable for them and many die out. Your role will be to guide the peoples to fertile lands where they may settle down and live a more stable existence.

Of course before that can happen I need to implement user interaction!

I could make the generated map much nicer than just random noise.
