Peter Ebbesen said:Forum sentiments from EU1, EU2, and EU3 indicate that most people do not consider managing an overwhelming number of provinces harder, more challenging, or more fun - in general, the sentiment is that it detracts from the game-play experience.
Arguing for fewer provinces and the un-fun nature of having to deal with a huge number of provinces may sound a bit weird coming from one such as me with a known preference for playing extraordinarily large nations in any and all Paradox games, but it does seem to be opinion most often expressed viz. actually playing large nations: from a certain step (differing somewhat between posters) having to manage more provinces adds nothing to the challenge or difficulty, it only adds to the tedium. Having heard this time and time again in all the EU games, the HoI games, Victoria, and even CK (though more often expressed concerning scaling courts), I've become an ardent believer.
As such, the number of provinces should be determined such that an average player playing a major doing fairly well, but not spectacularly, should, in achieving this, end up managing just enough provinces to feel he has his hands full and no more. Making provinces smaller and more numerous than needed to support this paradigm will only enhance the gaming experience of players playing minors and players focused on realism and history over gameplay, while it will harm the gaming experience of those playing the major nations the game is designed for.
Of course playing larger powers with a small number of provinces will be a joke, considering the level of the AI especially in 1.0 versions of the game. Paradox games' replayability relies mostly on minors.
