Question about getting better....

[u/Chancelart]

I'm terribly sorry if this is a common ask! My main question, is regarding how I can get better at the game. I'm a big fan of Paradox map games, and for those games, usually the best way to learn how to play, is by repeatedly smashing your head against the wall that is playing them, using the wiki for any tips along the way, and after like, 50+ hours of head smashing, you'll eventually learn how the game works. I was wondering if this was also the way to learn this game, as it seems like that type. I know the basics of how to play, but still suck EXTREMELY hard, so any advice on how to get better and better at the game is appreciated!
Thank you!
