I wanna try writing crossover fic but I don't really know what the pitfalls and problems are. Any open advice on the topic?
So I’m going to start off by saying that most of my recent crossovers have been sheer crack fic, so… I’m a bit out of practice with serious fic. I’ve been nothing but self-indulgent in recent years, so let’s see what I can do.
Note: I’ll be focusing on my preferred form of crossover, which is characters from one fandom encountering the world of another. Fusion fics (e.g. the Hogwarts AU) are their own category.
