Very interesting stuff. You could say I got somewhat lost on my trek along the EU site and ended up here. I'd nevertheless like to add my 2cts about Industrialization.
I understood from the FaQ that AoN is an extention to the original game. That should make it possible to create a Grand Event of Industrialization based on economic development in earlier centuries. Among the more obvious indicators of the high infrastructure and trade, perhaps a strong plutocracy and much money, I think that the degree in which improvements like governors and chief judges increase the demand for goods like Iron and Cloth. To put it in a crude formula: trigger= demandI/demandB > x. demandI stands for the increased demand for Iron and Cloth due to governors and chief judges, while demandB stands for the basic demand for Iron and Cloth without these improvements.
Needless to say, the evnet of industrialisation could cause large fluctiations in demand for goods like coal and iron. It would be really cool if you could add such a product like coal, though since I haven't any clue how much work that would take or if it would be possible at all..
