Actually, i haven't really run into that too-huge AI army thing; except for China, which should have the manpower to recruit 300-400 divisions, and Austria, which has conquered alot of territory, and thus their total humber of divisions isn't too fa out fo the ballpark. Most nations have less than 80 divisions, which is fair (i only have 32 carefully horded divisions, built up over 60 some years, thanks to manpower from the Belgian Congo and Belgian Sudan) I'm the 10th strongest military power, so at least i don't think that things are too screwed up.
Anyway, to be on topic with this thread. i can't reply to many of the things brought up in the review/thread. i've experienced that automatic tax revenue shift thing, just figured it was part of the game mechanism, not that is seriously impacted my revenue.
To give this game a little review:
Amazingly, i haven't experienced a single CTD, which is in big contrast to EU2, so Thumbs up to the developer!
Music is fantastic. the varying classical pieces/military marches are perfect for this game. another Thumbs up to Paradox!
Letting the computer handling trade saves me alot of trouble, until i needed to start buying items myself, or stockpile some of my own resources for big purchases and every time i tried to set the buy/sell level, the computer would overrule my trade order. then i discovered that you can switch off computer control of individual goods/resources traded. Overall, trading/ budgeting/ etc... isn't too difficult to figure out when you get the hang of it.
I like the greater graphic detail of the main map, and find the political map view very useful. Another thumbs up
i don't read the manual usually anyway, and only briefly skimmed through this one. can't give an opinion of it as a result.
as for military/power potential of nations, a minor nation like Sokoto hasn't much chance of becoming even a regional power; then again, it should be hard to colonize/claim half of Africa as them(I did it, but only with massive help from Cheat Codes

) I'm the 8th greatest power in the world, which isn't bad. main problem is that i neve have spare manpower, couldn't even field half the divisions i have without african manpower which can be magically converted into higher quality Flemish Manpower (this is a good exploit/bug, and should not be fixed). overall though, nations which shouldn't get very powerfull don't (Austria excepted).
Biggest game issue that i see is colonization/non-triggering of certain events.
The USA always goes on a mad colonizing spree from 1848-1860 and, when the civil war doesn't oocur, like in my current game, there is absolutely nothing to check it's progress, and if i had not started colonizing way before the historical time, there would have been no Belgian Congo or Belgian Sudan, they would simply have been 2 more US colonies, along with Okinawa/most the of pacific islands, nigeria, cameroon, chad, niger, algeria, etc... to keep the us out of more african territory, i had buy and sell and trade most of equatorial/southern africa to those nations which should have chance at colonizing those areas, as Belgium i could have owned half of the continent by the 1860's. though instead i sold/gave/traded most of the territory apart from Congo/Southern Sudan to Prussia, Britain, Ethiopia, etc...
While in my other couple of games the Civil War/Suez Canal etc... triggered, in my current game, alot of important events/things that probably should have happened did not (Suez Canal, German/Italian unification, British Intevention in Egypt(which likely didn't happen due to Suez Canal not happening), US civil war, etc)
Other than this, i see no major game issues, so overall i says kudos to the Design/Developing Team at Paradox for a great game, i don't feel competent enough/have not played enough to assign an accurate rating, so i won't.
Hope the developers find this very general review and my observations helpful and at least somewhat informative
(I wonder if Belgium should really be as a great a power as i've made it anyway?)
