The book is really well designed, its fun to read and there are so many good information on playing ttrpgs.
Its rules light, maybe a little too much for my taste but it was an amazing read. I will most likely give it a go when i get the chance.
The main reason i wanted this game was the spark mechanic. Its genius! I havent seen any other mechanic that has so many uses. I will use this mechanic in other ttrpgs too.
