I'm still waiting for the game to get a bit *better* to buy it but I'm afraid I must wait for an expansion at this point.
Don't get me wrong the game is very nice I loved Victoria 1, just because I love the history of 19th Century.
There is however a problem that EU3/HoI/Vic have: military.
In Victoria 2 regiments are pop based and here is the "unfun":
1. when a pop get too low simply the regiments "attached" are destroyed - even if during WWI ethnical and neighbourhood groups of soldiers were create, simply if you have 40k Berliners you just don't destroy a division because you can't replenish the ranks with Berliners.
2. linked to the above, FAR TOO MANY CLICKS to create regiments that are easily destroyed. You should reconsider a recruitment system: you have manpower (as it were in Victoria) - if you're not at war you send them to boot camp - you buy weapons, artillery, planes, tanks (if you have planes and tanks) - when the boot camp is over you send them to ranks.
3. linked to point 2. Regiments should be created as "standards". Id est you create a regiment filling in officers - simulating the reality when you create barracks where soldiers one day will fit in and HQ where high rank officers fit in. Given manpower, time to finish the boot camp and weapons, you can fill up ranks in the ragiment.
4. this part is easily moddable in fact: reinforcement speed ! Even if you have 40k soldiers it's VERY VERY unlikely they can't fill up ranks in a month. An example? usually American Civil War is fought by 40k soldier in CSA and 120k soldiers in USA. Where are the more than two million people mobilized? And the 300-400k casualties?
5. I don't exactly have an idea with this point but stack penalties and attrition seems to be unrealistic. For example it's impossibile for 2 armies (42k soldiers per stack) getting across Munich territory and get a penalty of 10%. Almost 10k soldiers dies in crossing Munich ? What the ... ?
That's my opinion. The military part is the funnier thing in game, problem is it doesn't work.
