I am moderately hyped for V3. Always thought V2 was the Paradox game with the most unused potential (especially now that Imperator was getting on tracks). Most announced changes I see as genuine potential improvemnts, like the more sensible way underdeveloped countries are to be depicted or the regional markets. Especially the latter should inrease accessibility greatly. Have more of a wait-and-see approach to the change on DLC policy they implied to make less, but larger DLCs. May or may not turn out to be true, but probably each DLC will be more expensive. At least the idea to wait on making decentralized nations in V3 playable only after the base game seems sensible to me. Those would not work well with the same mechanics as Prussia or Japan and forcing e.g. the Maori into those with the base game could only be disappointing. But there is so much potential for a better representation than in V2 at some point: I would love to cope with the end of the transatlantic slave trade and approaching European coloniesers as Dahomey for example.
The biggest problem with a flow system is that it's something you constantly need to pay attention to.
Victoria II gets away with it because it is really an economy sim with an occasional outbreak of war and rebellion. Imperator was Vici-fied and whilst it's a solid game now I'm not sure how fun it is.
If all the Paradox Grand Sim games get Vici-fied then Paradox's fan base will shrink considerably as will their profits.
I´ve always thought that generating monarch power each month and spending it once it reached a certain point was a stupid and needlessly complicated concept in EUIV. In Imperator Rome it was even worse initially, because you could not even influence the generation.
Had I designed that, it would have been more like for example the population cap in Age of Empires: The Bureaucracy of your country is capable of baseline administrative actions. Building bureaucratic buildings increases that limit as does new tech or the right advisers. And enforcing certain laws and maintaining buildings again requires administrative action, meaning you can´t have more than a set number of those at the same time. To illustrate that with an example:
Baseline is 100. You build 2 courthouses, each raising the limit by 5. You also have an adviser that raises it by 10% and advanced administrative tech raises it by another 10%. Gives you 132 administrative actions. Your currently active laws and edicts cover 50 actions, you have 3 forts each requiring 20 actions, thus you have 22 free actions. Now you want to build a stock exchange, but it would need 30 free administrative actions. So, do you decommission a fort, repeal some edicts or wait for improvements that raise your administrative capability or lower administrative requirements? Seems a much easier to grasp, more realistic and logical system. BTW, I would also reduce the use of said points in diplomacy in EU, instead requiring you to spend prestige (and introduce more alternative methods of gaining that, like maintaining cultural institutions at monetary and administrative cost).
