Masturbation is kind of tricky to catch, especially on high humanity girls and when the first island is fully unlocked due to the large area they have to roam. They tend to do it near where they are when their sexual need becomes the highest as long as nobody else is in range to ask them for sex, which often means while the player is on the other side of the island. Then you take into account humanity, which when high enough, will cause them to stop if they know you're there.I never saw her masturbating. For some reason I feel like my game is a bit broken, since she almost never does anything eventful.
Well, the question is whether it's worth the effort to make something like AA2 again. And by that I mean whether it's worth FOR THEM. Maybe it will require a hefty sum of money, but the amount of people that buy the game won't change much, so from financial point of view it wouldn't make sense. But it would be cool if they made it anyways. At least some sort of remaster or something, so it actually works properly (i would rather play AA2, but it keeps crashing)
It would definitely be worth making a new Artificial Academy, the demand is there in both the Japanese and western markets, both of which Illusion is now in.
