Is writing a Pokemon Mystery Dungeon fanfiction cool yet? I don't know, but I think I might try it. High quality writing is explicitly a non-goal, but if you want to read it, take a look here!
A long while ago I had a writing pad where I'd write little stories. Often they sounded more like excerpts of stories than complete pieces of their own though. I found them quite nice to read so will run an experiment of doing a similar thing digitally, linked here.
