Since you're way more knowledgable about Italy and the Serie A (at least, when it comes to the behind the scenes stuff), maybe we can talk about this in private?
I wonder how they'd do against Gauntlets and Nimrods with more powerful engines and more guns? (Britain has more powerful Mercury and Kestrel engines than those fighters are fitted with so why wouldn't they re engine them with a war to fight)
What do you mean by "the agricultural revolution"? I'm assuming you're not referring to the Neolithic Revolution, since there really were no cities (let alone megacities) before then.
