I think we've all got different things we like, and that can push our desires in different directions. But there HAS been a push away from 'enemies as a threat' into 'enemies as an obstacle' in recent years, with the beat-em-up becoming focused on c-c-c-c-c-combos and character progression rather than map knowledge and damage avoidance. Which has kinda pushed aside a lot of interesting enemy interactions, which is the kind of thing I love to see. I want an enemy I can look at, who reacts interestingly and isn't hidden by effects. Even as we've gotten squat and round girls, girls with helmets, muscle girls... a lot of them just sort of take hits and get comboed like they accidentally went online in a fighting game.
So even though I have the strange and unusual taste of 'slim, leggy, boobies and ass' I really feel it when people talk about the lack of diversity. I don't think it's appearance, I think it's behavior and interaction. I don't want enemies that can kick my ass, but I am aligned with people who do, simply because I like interesting things to happen. It's actually why I love bomb throwers! They throw their bombs , wait, and then have to run away! That's interesting, and has all sorts of ways it can wrinkle. What if they looked around in a panic before they ran? What if sometimes they tripped and took a while to get back up? What if sometimes they just surrendered? It's something to bite into.
