@_sims_Yimi I write first, then take screenshots.
I wrote this story up about three years ago. The idea just popped into my head one day and I just started writing and before I knew it I had like six separate stories. Then I kept coming back to it and I got attached to all my characters and the story. I was really chicken to put it out there and sat on it for a while until I decided to put it on WP and the forums.
I'm not an outliner, I just start writing down what is in my head in a word document. It turns into a rough draft, and that's what I use as an outline. I don’t recommend it because it's kind of time-consuming, but it seems to be what works for me right now. Originally, I was going to use Sims 3 for screenshots because of the whole ghost hunting career, but I like the look of Sims 4 better. I rewrote some stories to fit into sims 4. Hailey, Ian and Vern are pretty much the only characters that haven’t changed much as far as backstory/personality.
I do a lot of rewriting because as I write and read my rough drafts I come up with new ideas. The barebones plot stays the same, but how the characters get there might change. I usually know who the villain is from the beginning, that doesn't change, and I think that needs to stay like that so I can drop hints to who it might be or red herrings to mislead. I am not afraid to scrap an idea or scene if it doesn't make sense or I don't like it. There are a few things that are pretty set in stone, like character backstories (I also plan on doing some flashbacks). It's kind of organized chaos because I have so many word documents with different stories/endings/scenes.
Screenshotting can be a pain because I have a specific idea in my head how a scene will play out, but sometimes I can't find poses or the game won't cooperate with me. Then I have to rewrite a scene or change it to make it work with the game (I'm getting better about not writing scenes that I know won't work in the game). And then sometimes my sims will do something funny or different from what I intended, and I will write that into the story (that doesn't happen very often since I've turned off autonomy and max out all their needs).
