There's a game called Banished that has cycles to it unless you are careful. The economic model is complicated enough such that if some event hurts your ore miners, then your ore output drops, when your ore output drops then your blacksmiths farming tool output drops, when the farming tool output drops your food output drops. When your food output drops, your food stores drop your people start starving. It can cause a population of hundreds or thousands to drop to a few dozen. But all the infrastructure you built for your large city becomes a burden at that scale, and it take longer to grow to your old size than it did the first time. What I found fascinating is after playing for a bit you can start to see these cascades start early and try to stop them and still fail. All you can do is try to efficiently route resources as you watch your entire city fall into decline.
