You know, the funny thing is that I remember talking about the possibilities of a good Harry Potter RPG a while back.
My idea was this: create a character that enrolls into Hogwarts at the same time as Harry and the other main characters, but never really makes contact with them. They would be there for fan-service and maybe you can watch them do their thing at the crucial points of the story, but otherwise it would not be a "Harry Potter" story, it would be a "watching he events of the Harry Potter through the eyes of an unrelated character".
The gameplay aspect would have been a raising simulation type of deal. At the beginning you build up your character, including your origins (pureblood or muggleborn, early life, starting bonuses, etc.), choose your House, which decides your interaction with most of the cast, then you go through the school year while deciding what to focus on. Do you want to be good at academics? Become a Quiddich prodigy? Will you befriend other students, or would you focus on getting to the good side of the teachers? It would essentially be a time-management game at this point, where you have to make your priorities. In the meantime stuff happens in the background according to the books' scenario, and sometimes you might have to contribute to some solutions yourself. However, it would start out very simple and straightforward at first.
Then, as the story progresses, you would go through the next school year, and the next, and things would get more and more complicated. Sometimes you would need to take sides on inter-house conflicts, have your own adventures while exploring Hogwarts, collecting your own assortment of magical items, form lasting friendships and even romances, all the while still continually raising your stats and refining your character. Then, at the very end, the war breaks out and you have to choose a side, including option like hiding with your friends, running away, fighting other wizards, using the connections you have made during the years, etc. Practically, the entire game would be one huuuuge buildup for the final conflict where everything you do has some minor effect on how you would survive or even profit from the events of the books.
Now, all I need is several million dollars for the license and a talented team of developers and we are all set.
