Great to have word-of-god confirmation on what I've been believing for so long. There is much sense (at least for the setting) in this ruleset, IMHO.
I will now blather on about my opinions. I am entitled to them and I don't want to change anything.
I really don't think Private IC should be usable in research (as I've said so many pages ago), nor should primarily historically private-done technologies be attainable through research (I'ven't been keeping track of this NES's tech tree, though, but I've seen the tech sets of other variation-NESes), but I think civilian technology should be tackled by
trading bloc -- a network of nations trading (in a completely free market world, that would be everyone).
That is to say, a nation with high private IC should be the civilian tech leader of a trading bloc (except those with specific controls on technologies and high-tech items, or with generally high protectionism etc), while the others lag behind but not by much and the total ICs of everyone determining the general tech level of the trading bloc. Of course, this would only apply not only to free market trading blocs, but to communist trading blocs as well; just replace "private enterprise" with "public spending" (but just the public spending that's not directed to some great project; the "general-use," unspent public spending).
Blah blah blah, and blah blah blah.
