On second hand books, the Fabled Land gamebooks are almost a solo RPG/analogic RPG video game which can be played with no power :).
Also, a lot of the older books on technical terms are far better because the skills on similar education levels were far higher back in the day. For example, today's Electrical Engineering books from the first year in College were on par on senior HS years.
