My comment will be relevant for all games in the Total War series. Here everyone will find something to their liking. If you feel the talents of a commander, gather an army and go to war. Or maybe you prefer peaceful development, then develop the economy. But one cannot do without the other: without a good economy it will be impossible to maintain many armies, and without at least several armies they can come and conquer you.
Yes, this game has its shortcomings, but when you launch the campaign and start playing, you sometimes sit for 2 hours, or even more.
