Okay. So, you start out with Bavaria. Sweet little Duchy, you think. And you're like, whatever man, invest money into stockpiling beets. And it just so happens that this is a trigger in the black box ruleset for boosting income x2. So you're like, COOL, and you keep storing beets because it worked before. And suddenly you have an income of 10x the surrounding nations because you gamed the rules.
Suddenly Bavaria, despite not substantially increasing in size, is able to launch a destructive war of conquest over the face of the European map. Its beet-fueled hordes crush my poor Poland-Lithuanian dual monarchy, despite the fact that there is no physical way Bavaria could generate more wealth than me. I, meanwhile, have just been minding my own business, generally being a decent dude, but hey, I didn't find the beet turbine loophole.
And suddenly, despite being a reasonably competent ruler, I'm out of a job.
You'd pat someone on the back for that?
