The Character Creator is a Free Tool For World Building
I talked earlier today about using character creators for game creation, particularly visual novel. I went on a hunt, first on Itch.IO, but then on Google. It took me less than a minute to find a free 2D character creator. I made a video of it being used. I trimmed the video so you didn't have to do a click play to a full Monty scenario. Check it out though, I was able to customize clothing, facial features, facial expressions, and body types.
