M.T. Black
Hero
I've been thinking about that as well. A book twice as thick as AoA would still be thinner than other (non-RPG) books on my shelf. The digest size makes it transportable. Hmm... we'll seeI really like the digest hard and soft back of M.T. Blacks The Anatomy of Adventure but I wonder what that would look like with 500 pages!
Though I think breaking it between two books between chapters 6 and 7 would work.
