Do you like caricaturized leaders in the game or would you prefer standard looking (more realistic) versions?
Well, charicature isn't an accurate description. Charicatures a have exaggerated features, not entirely new ones, as is the case for the old version of Teddy Roosevelt, as well as for Victoria, Catherine De Medicis, Qin Shi Huang. But, anyway, besides the old Teddy, and to and Victoria, I don't mind this style.
Anyway, to be honest, what bothers me the most (now that walrus Teddy is no more) is the backgrounds. I sort of appreciate them because they should make leaderscene backgrounds easier, and possibly more enjoyable, for the modding community to make, and some of them look quite nice, but I preferred the dynamic leader backgrounds from Civ 5, particlarly the ones for Montezuma, Harald, Nebuchadnezzar, Askia and Gustavus.
Overall though, I probably preferred the Civ 5 style, but I suppose a change was needed. Off course, when it comes to Civ VII, we'll probably have an entirely new style altogether.
