I disagree making so much animations with Annie, I'd much rather see more normal enemies and animations with the main character. Not many players will guess that Annie has animations at all, and even if you give hints at it, having to find exactly in which level it is possible to have XXX enemy follow you and fuck her is starting to become extremely specific conditions which most players won't bother doing at all. Compare this with the 3p/4p/5p animations, they are specific too but at least you can stumble into them randomly while playing and find them without having to read a walkthrough. I think it's good to have animations with Annie as easter egg but having more than 1-2 animations locked behind this mechanic sounds exagerate.
