Well, I have over 200 hours of playing EU IV by now, both single and multiplayer.
I don't really play with much mods, because this game is way more intresting and have so much in-depth features than EU III without expansions, but there are still some things that can be further developed, balanced or just fixed.
To begin with (the real point of thread) I'd like to see an option, disguised as a building, to change province's trade node appurtenance. The province that you want to see in another node must obviously border the node (the one you want to attach the province to). For example it would cost base 50/100 diplo points and cash around 100 denars, depending on: if the province is "Important centre of trade", or is placed by the sea, river, simply if it gets any boosts you'll pay more, also province trade power is raising the cost. To protect the game from beeing unbalanced the cost of such action would double every time you do it. That's the feature I'd like to see implemented somehow.
Culture - base factor that stops me from EU III-like playstyle where you could simply conquer pretty much everything (Dat HRE though). Here you must deal with culture, which is awesome and realistic feature, but there one thing that needs a fix I think. Accepting culture and "Sending them to work on field" event should more controlled or triggered with player's acknowledgement or even a decision. There could be a option to i.e.: "Increase the funding on cultural unification" which would increase intollerance and add base revolt risk to every province that's culture is not primary, but in return you'd get cheaper price of changing the cutlure by, let's say, 10-20% - so if you get province with base tax 10, you would use only 225 or 200 points instead of 250. Also if the culture that is not accepted is at least more than 5% of population can get a status of minority, which would mean that they have lowered the revolt risk, for: cash, diplo power and it would lower taxes, production effency, trade power and other cash outcomes by 17% (it would mean 50% lessend taxes) - so this idea means: No revolt risk for unaccepted culture, but further penalties for taxes. When the population is more than 15-25% you can set it as a accepted culture within great cost of cash and diplo power, but the requirements should be like: true faith in every province that has the culture you want to accept, at least one administrative building in province like court for example and max cultures that player can accept is (?) somehow determined by - numer of provinces you own, percentage of people which are of primary culture and number of provinces that have the culture you want to set as accpeted but is not within your borders (what I mean is: if there's a country with 20 provinces with this culture and have 2 provinces, which more that metioned 15-25% of your population you pay a lot more cash or something, some kind of penalty).
I'm aware that these feature aren't "polished", hard to implement and also threathen the game balance, but I'm sure (esspecially culture fix) would bring some flavor into the game. i hope some of you would like it
