Harry Potter RPG for kids

The boy has asked me to run a game for him and his friends. He writes:

I would like my roleplaying game to be about Harry Potter.

I think the setting should be at Hogwarts and I think the characters should be very good at magic or not very good at magic.

I also think that the scene should be a mixture of quidditich and magic class.

Discussing it with him he seemed happy to choose a different school, perhaps in the USA. So I'll probably set it at the Salem Academy, which is mentioned very very briefly in Goblet of Fire. Probably for simplicity we'll end up with the same houses but need to ask the kids that.

From discussions with peaseblossom it appears what he really wants is to focus on magic class and quidditich and he doesn't care about having a big bad. He also wants to go through all seven years. That seems to lend itself to a nice narrative arch of start of school, halloween, christmas break, quidditich cup, end of school. Which is pretty much how most of the books are organized.

Mechanics, well definitely will have to whip up something simple. peaseblossom recommend using a class schedule to build skills, and that seems reasonable. Throw in some virtues and we're all set.

Now to invite his friends.
