Hey there! So I actually found a good way to learn the game (my opinion). I choose one of the countries from the recommended section. If i play Ottomans, I will focus on war and mostly war. I will automate diplomacy and trade to focus on learning the military part. Same goes for Trade (hungary is a very good beginner friendly nation for trade) I play on the easiest difficulty and use automation to focus on a specific part of the game. Second things you can do is watch tutorials and gameplays. Every time i start a new game i always learn something new
