Did anyone notice this:
"Paradox has found an excellent and playable compromise. First, technological developments are broadly characterized as "army", "navy", "culture", "industry", and "commerce" and ranked in logical order - you won't be able to develop advanced steam engines before basic steam engines for example. Each state may select one research project for development at a time from a randomized list of five available choices. Further, what projects are available in this list of five is based on the country's Intellectual Establishment - representing the cultural focus of the country's research efforts. An "Industrialist" establishment will always have three choices from the Industry tech list, one from the Commerce list, and one selected randomly. You start with a historically-appropriate Intellectual Establishment, but you can change it periodically for a cost in victory points. Thus Paradox has found a way for players to guide their research development generally, while still offering them a degree of novelty and replayability in the actual applications being researched."
That is very innovative... clever Paradox... it looks like a lot more is tied to the form of government you have than I could have imagined!
