One thing I've been curious about since seeing the GB quicklook is resource depletion. For example, what happens when your city (and ultimately your entire region), runs out of water? Does it just add a negative modifier like unhappiness or does it act as a sort of time limit on how long your city can survive? Do the water tables regenerate in any way that allows you to create sustainable consumption or is it just a inevitability that you cannot avoid?
Not sure what the best balance of realism and fun I'd prefer is. I like the idea of limited resources and making strategic decisions on how to best use them, but realistically, running out of water should be a city ending disaster, not just a negative modifier on some meters. Unlimited water isn't appealing either, so I'm not sure if there's any way to split the difference that would satisfy me.
