Something like HOI4 is this CK3? If so, I'm already doing exactly what you described in Victoria 3. I like war with economy more than normal war in grand strategy.

quad-digit hours!? Wow tyvm for your comment, it is incredibly valuable.

First of all, thank you, victoria 3 and crusader kings 3 seem very similar to each other except for the period. Instead of playing the same two games, I'd say get one grand strategy, one real time strategy and the other mmorpg. :D
