It's a valuable starting point for world and story-building. As a Notion Noobie, I've made minimal customizations: I created an outline page as a glossary of the story and hyperlinks to other sections in the document. Overall it feels too broad. Continuing to adapt to adapt as a mind map.
I just downloaded Notion Story, I haven't had a chance to use it much but I am amazed at all the extent of the work and the efficient system made available by Bluemoondragon Productions. Great job!
The Notion Story Wiki provides a customizable framework for world building and writing that teaches you how to build off it to fit whatever needs you have. I just had to follow the included tutorials to build what I needed on top of an already substantial collection of templates. The creators put a lot of work into crafting the Notion Story Wiki. Couple it with the performance of the Notion App and I've replaced a lot of redundant programs and services (and reduced a lot of subscription costs). I'm more than happy with my purchase!
