This is great to see. I've always been a fan of Storybook but have also struggled with it a lot. Each new release has reduced the struggle. To their credit, it's hard to drop something like Storybook into a project because frontend projects have almost no rhyme or reason to how they are made up (well, React anyway, which is what I mostly work in).

I am also using Storybook for my game dev. I wrote my own renderer for my engine and so the entities in my game have stories. It makes building new entities and seeing how two entities interact so much nicer and faster.
