Like in "My empire isn't round enough, let's attack someone" ?
Being French, I have to build Notre Dame and the Eiffel Tower in Paris and nowhere else whenever I can. I also rename Marseille, Reims and another incorrect city's name (can't remember which one right now). When playing Napoleon I feel compelled to attack and vassalize anyone on my landmass, especially Russia, even if we're friendly. I'd also like to find a way to rename marines "fusiliers marins" and mech inf "VAB" for the French without having to do it by hand for each unit, but I'm just too lazy to search how.
More generally, in the endgame I have to build every building in every city even if unneeded, and I run some 0% research turns to upgrade every unit. I also try to have the highest approval rate and life expectancy.
