In your own space, put some favorite characters into an AU, fuse some favorite canons together, talk about your favorite AU/fusion tropes, or tell us why AU/fusions aren’t your cup of tea.
I'm not sure what to do with this challenge. I've focused on original fiction rather than fanfition, to the extent that I have had time for writing (and reading, for that matter), for a very long time. It's not that I object to crossover fanfiction or exploring alternate ways things can happen, just that there's only so many spoons, only so much time and energy. Occasionally I've come a bit that I very much enjoyed. But I don't write it and don't seek it out.
Alternate universes can be fascinating in general. I read a lot of urban fantasy, which is basically alternate universes compared to today's world (It's certainly alternate to have a world with overt, flashy magic that is otherwise much like the one we live in.)
And I also have really enjoyed working in shared universes, and I miss the creative boost of bouncing ideas off other people in that kind of shared endeavor and getting inspiration from their ideas and thoughts in that cooperative creative mindset. I miss it, especially Torn World, which was very active for a while.
Similarly, I miss role playing games, both tabletop and LARP. I'd love to find a group doing a game via zoom where I could sit back and play a character. I don't think I could do a good job running a game while also writing novels (I think either the game or the fiction would suffer from lack of mental bandwidth), so I don't want to try to gather a group around me, at least not at this time, though I miss running games too.
