I want Bully, but set in Hogwarts.
That... is a pretty good idea.
Honestly after hearing bad things about Bully my first experience with it is that it is... underrated... in many ways amazing (and revolutionary in one respect for a T-rated game)
Not that I love ALL aspects of it. I mean I can't stand the lunch lady (and all her quests)... and it seems like the game cannot create a villain except to make them almost wholly unlikable (Well sort of... the main villain is sympathetic... so much so the ending actually is a huge WTF moment for me because he just disappears)
In many ways the controversy surrounding the game is poetic given the entire point of the game is how everyone just assumes the worst out of our hero.
Really, I am surprised that the bullies in the books (harry potter) are so benign... Shit, I know I would be doing some horrible things with magic involved. (No, not a bully per se, I would totally be an anti-bully/class clown though.)
Just picture it: Magical automata that resemble Smurfs (without actually being) invade Snape's potion supply cabinet. Are immune to magic (actually, it forces them to reproduce like water does to mogoui(sp?)), Can only be destroyed with kindness. (The honest, genuine kind that Snape is incapable of.) Grow horrible mushroom houses all over, and sing out of key.
For people like Malfoy, very special gender neutralizing (as in, ken doll smoothness) curses, like "Androgynus!", or being followed around by little magical flocks of singing bluebirds, Disney Princess style.
Maybe a curse that causes him to talk out his ass every time he acts like a little shit... Or perhaps make toilet flushing noises. Things like that. I would be like the evil version of Hermione Granger.
What do we get in the books instead? Malfoy just being a little pompous shit, of the ordinary, benign kind. There is so much wasted potential there.
