I knew gamebooks dated back much further than Choose Your Own Adventure and Steve Jackson's Melee and Wizard solo games. I used to play educational logic "gamebooks" back in the early 1960s. But it turns out that "Alan George"'s Treasure Hunt not only anticipated all that by a further two decades (it was published in 1940) but also sort of pioneered the graphic novel gamebook genre that I thought Russ Nicholson and I had invented in the early '80s.
Prior to that was Consider the Consequences, a gamebook of life choices, love, marriage and careers by Doris Webster and Mary Alden Hopkins, which came out in 1930 and is now available on the Internet Archive.
Much more up to date is a new(ish) open-world gamebook called Traquelero: A Quest for Happiness, by Othniel Poole. It seems pretty hard to get hold of, which is a shame as the concept sounds fascinating. No dice, no stats, just a character journey to explore. Effectively a walking sim in gamebook form? I'd like to try it and find out.
