Least favorite part of my favorite game: AI in EU5. It doesn't know how to do anything even vaguely remotely historical.

Favorite part of least favorite game: I honestly don't have a least favorite game, but I guess HOI4 might count, since I hate vanilla HOI4 and only play modded. I will begrudgingly admit that the national focus tree system in HOI4 is a genius invention for allowing for historical simulation. Shame the rest of vanilla HOI4 is a wargame whwich doesn't care about economics or politics,
