>>2074075>Laws. They're obviously intending to add some across the board based on the various laws Admin realms currently have, but fighting with your vassals/council is what kept the game interesting over multiple generations. As it is, its a prestige cost.
>Raising troops/war.Civil wars and even external ones were dynamic. You had to balance/avoid keeping a vassal's troops raised forever and you could cycle through different vassals to maintain a positive opinion. During a civil war you had to group loyalists together while avoiding rebel armies, this also made every civil war different.
>Technology/buildings.It wasn't great in 2 but it was fun spreading tech through your realm, and advancements didn't just apply to a culture group as a whole. The way certain tech was required for better laws was also a cool way to tie things together. Being able to pick where you spent your points was great too, I know you can do something similar in 3 but its legit just a pick and wait game, in 2 you could save up and burn points on the next tier of legalism or majesty for direct bonuses like an unlocked law or extra opinion.
Buildings in 2 were a silly mini-game and I understand why they simplified it but at the same time, let me build more than X-number of buildings until I increase development. In 2 I felt like I was improving my realm with each building, in 3 its more like waiting for development to grow so I can build something. At the same time, increasing prosperity and spawning a new barony title in 2 allowed me to make anywhere on the map my golden paradise. This is absent from 3, banonies are predestined in number. You want to make the Isle of Man the Constantinople of Britain? Sorry bud, you've only got two provinces/baronies.
There is a lot a like in 3 as well, dont get me wrong but - Also, de jure drift. Holy fucking shit. Is it so hard to understand that I want to be King of multiple titles without my main title subsuming my secondaries? FIX PLS
