-The naval issue is not explained, it has taken god and hours for there to be a consensus based on evidence that you need at least one ship per division.
-You cannot exchange provinces, not even give provinces to your vassals.
-The idea of markets is very good, but poorly implemented. Being in a market being the small power is boring because the owner of the market does everything and you don't know exactly what the needs of your country are, only your market. This is serious when you play with a vassal country, that until you become independent you don't know the real needs.
-What is the use of sinking convoys if when you do it your fleets stop looking for convoys? It's very easy/quick to rebuild those destroyed convoys and before you know it the enemy has re-stocked. As long as the enemy has the resources and the buildings full of employees, the convoys will not be a problem to have them again.
-Protecting the coast is of little use, the enemy disembarks as he wants.
-I cannot isolate neighborhoods from metropolises because intra-market transport is automatic and omnipresent. The Philippines will always be connected to Spain as long as they are in the same market.
-The political system is very simple and irrelevant, its problem is that you can ignore it without consequences.
-Buildings can use rail even if you haven't built it in the province. A Galician mine will use the train even if it has only been built in the Balearic Islands or Puerto Rico (perhaps even Cuba, which is a colony).
-Playing with all countries is the same. I have played with Chile and it is little different from playing with the Philippines, Spain or Russia.
-It is super easy to have a healthy economy, beyond the quality of life or less efficency of the pops there is no repercussion that you lack materials.
-Colonization is a joke. UK taking in 1837 Western Sahara, Russia New Zealand, USA Patagonia or two powers colonizing the same place without any type of tension, they are only two powers colonizing as far as the other will allow them.
-Pops are assimilated/converted very quickly.
-A lot of information about the economy in the game is missing. Being able to see the production of your country (not market), or at a glance more factories.
-There are few events and therefore they are repeated a lot. Countries do not feel unique for it. There are also no decisions by country with a few exceptions.
-The unifications are practically automatic.
-Rebels? Is that eaten?
-Micronations in infinite civil war because they have no divisions.
-Do not expect to feel the world alive because they tell you that one power has declared war on another or the war has ended with the result. It doesn't matter if you have an interest in the area, you won't know what's going on if you don't see it yourself with the camera. Europe could burn and you may have lost the war and not know the result because you were trying to build a banana tree in the Canary Islands.
-Most of the important things such as a route no longer being profitable or your country dying from not having paper are not communicated to you if you do not hit the notification ball and then the missing supplies submenu. Every so often you have to check the notifications if you want to maximize everything.
-The tutorial is a good idea badly implemented again. It doesn't tell you long-term goals (although in a normal game you do have that option). One goal is to sink convoys but there are people who have never jumped on it and stay on "keep playing and new missions will appear" without telling you what you have to do to get them out. Others have improved relations with X nation and the tutorial now tells them to increase them back to 50+, so you can't use what the tutorial itself tells you to improve relations.
-The approval of laws is a great RNG in which you barely have any decision-making power and cannot do anything to get it approved.
-The interest groups can range from trade unionists running for the patriotic party to aristocrats for the socialist.
-The elections are a joke, you can practically form the government that you want.
-Austria, Russia, Ottoman... very stable countries in which it doesn't matter if each one has a language or culture. And we return to the point from before: it doesn't matter who you play with, everyone plays and feels the same because there is not even the slightest flavor.
- Migration makes no sense. There may be a time when more people migrate to deep Siberia than to Colorado, Kansas, or Argentina.
-Diplomacy is very difficult because everything is based on -100 and beyond trade agreements and improving relations it is difficult to do anything else.
-New journal entries/available decisions are not notified. I didn't know I could do an expedition to the Nile until I decided to build the Panama Canal and accessed that tab.
-There is no military access.
-The generals change front like the one who changes his shirt.
-When a front collapses and is divided, the army is not divided, leaving one of the fronts at the mercy of the other if it has more generals.
-There is only one battle per front that is very good to fight for an island, but that doesn't make sense on big fronts like the European one.
-The abstraction of the ownership of the means of production is absurd. I can make a factory publicly owned for free, give it to the capitalists for free, make it publicly owned again for free, and then put it into stock and it will all be without exchange of money. No bourgeois complains that the factory is taken from him or rejoices that he gives it away.
-The infamy system has little effect on the game. The AI is quite passive even at high levels.
-Two countries at war and that have no border between them will never stop being at war because there is no military access or a counter.
-The diplomatic options are scarce, less than in other games and that is a game of diplomacy (and economy, I know).
-Commercial ports (teatry ports) are useless, maybe it's a bug.
-Westernization does not exist, and although the recognition system is well thought out, being recognized has no weight or consequence.
-You can transport hundreds of thousands of men in a month from one end of the world to another without problem or consequence.
-AI production decisions leave a lot to be desired.
-FPS drop after a certain date when zooming in and out.
