Killer doc. As a beginner trying to get started in TTRPG design, this is incredibly useful.
I printed this off as an A5 booklet, and have been madly highlighting and adding notes for myself. Very fun. My only problem is that at 27 sheets, it's too hard to staple 😅 next time I might print it off as 3x9 sheet booklets.
Also, I would be super interested in buying a soft-cover of this, if you ever feel like selling one :)
