1. Game just got a massive overhaul, graphics and interface/gameplay wise. So the content is still being caught up. Should be pretty much caught up after next release.
2. The animations do change like you change clothes. The process is all automatic and takes about an hour of rendering without me even being there. So if I want to add a new outfit for the Teacher, It will just take an hour to produce all the scenes for that outfit. So when you click that new outfit, all the animations and still images will be of that outfit. System is real easy.
3. Time will tell if the personalities work out. But I think it's a cool idea, and I'm already halfway done on it for the Teacher. Since I did that pretty fast, I don't think it will be as much work as you think it is. Not like I sacrifice anything by just trying it.
