@YuffieProductions I don't remember why I started writing in present, but I find it slightly easier at times because it's kind of like how you think-ish lol Some stories just have to be in one tense or the other though - for example, I have one story where the characters die in the end, but it's first person narration, so having it in past wouldn't really make sense (However, I didn't realize this until after I had already started it in past. Oops.)
My roommate and I are working on a collab right now, and it's the most planning I've done so far - and we're not even done planning yet! I typically just wing it on my own stories.
