#1 - this is one of my fave ideas, so if anyone ever runs it, they really need to link me since I want to see it in action!
#2 - Right?! I also like the idea of there being variety amongst the students. Since Hogwarts is a highschool, you only get 11-18 year olds. But there's a lot more room to play all kinds of different characters and I like the idea that you could have a class with a 16 year old and a 70 year old both learning the same thing. The life experience some of the older characters would bring would be really fun to explore. And also! The difference between Wizarding plays and Muggle ones is definitely a question I want to see fleshed out somehow.
#7 - YESSSS WIZARDING UPPER EAST SIDERS. We're still planning on doing a game based on that idea (idk if you were around when I brought this up!!), I'm just trying to get myself organised between work and everything and avoiding modding anything because HO SHIT, NO TIME.
