It wouldn't work as an actual book.
Seriously?!¿¡ How do you publish a book that has multiple characters to choose. Depending which you choose the story changes, in some cases quite dramatically, it can also change the outcome of said story. Not to mention the choices that come up which also change how the story proceeds. In some cases, like a few in Adastra for example, can end the entire story even though you're only halfway through. How could that be possible with a physical paper book 📜 📖 🤔. A Kindle or similar eBook would work, but not traditional ones. If it can be done I'd love to hear how it's done as I love learning about new shit.
