I found it rather silly how having a large amount of poor provinces in EUIII would kill your tech rate. That would mean that a European power like Sweden would lag behind other European nations, even that's not historically accurate. In fact, weren't some of the larger countries also some of the most technologically advanced, such as China and later England? Going by EUIII rules, England's technological advancement would have slowed down significantly due to her colonies, which I don't believe was ever the case in reality.
