If you check the early release folder [patreon+], you should see Easier Solo Play as a file.
This book is a 92 page PDF, it is not a set of rules, it is just tips and advice. When it is released it will initially be $4.99, but then going up to $7.99.
I was originally inspired by Sly Flourish’s Lazy DM books, his is shorter but when reading it I could not help think that what he was suggesting as being revolutionary was run of the mill to us.
As each chapter is one tip, and each tip runs to about 700-1000 words, this was a book I could easily work on where ever I was, waiting in the car, at home on the sofa. It was not like solo rules that required getting rulebooks out and clearing my desk.
