Eh, our brains still pick up on the same facial and vocal queues that even TLK characters share with actual people, being anthropomorphised and all.

Besides that, I have a theory that girls are often attracted to elements of character and personality to a slightly stronger degree than boys are. I do notice male characters like Sans (Undertale) and Kovu drawing that kind of attention despite their appearance, when popular female characters usually have a more logically attractive physicality.

See, I figured it was that people who meet the educational standards increasingly have the sense to not enlist, seeing as the last few decades of war have been of questionable moral value and veterans are not looked after once they've been used.
