I’m 53,000 words into a Harry Potter fanfic that fixed some issues I had with the seventh book. Basically, I object to how little the main characters ‘play to win.’

Example: Team Voldemort taboos his name, so that if you say it, his goons show up to arrest you. So everyone tries to stop saying his name. But here’s another idea. One person says his name while another hides nearby. After saying the name, the first person disappears, and then whoever shows up, the second person shoots them. Like, with a gun — a magical gun, if you want! Do that as many times as it takes until there are no more Death Eaters.

You get a very different book with characters who think like that, and it’s been a lot of fun to write.
