These books were incredibly important to me as an 80s kid. Was a voracious reader in general but absolutely loved these because they had replay value! I remember scouring through these on long family trips in the car to find every possible ending.
The parallels with modern video games are obvious.
The first video game (and one of the first programs) I wrote was a self-styled Choose Your Own Adventure on a C64 with ASCII art and maybe a total of 10 pages.
The only person who acted impressed by it was my grandmother - who had paid for the C64 - but that was enough for me.
In fact, this inspired me to buy such a book for my 9-yo son! They've grown in size, apparently (250-300 pages). Let's see how, in the age of omnipresent screens, he likes it :)
