Since I wanted some more test-data I asked ChatGPT to generate gamebooks for me and it was scary how good it is (and this is the old free ChatGPT). OK the stories are not very interesting as stories, but they branch properly and can be navigated and there is a beginning and sort of end and various little things to do. I think I will add a few as official example books in the GitHub repo (but I will make sure to mention they are generated and not meant to make much sense).
And since the style of Markdown it spits out is varied and not always quite written the way I do, I already found and fixed two bugs thanks to using this generated test-data. Definitely going to have it spit out many more stories to fill up my collection of test-gamebooks that I use for regression-testing.
# start_
You find yourself standing at a crossroads in a dense forest. You can't
remember how you got here, but you know you must make a choice.
To go deeper into the forest, turn to [deep_forest].
To head back the way you came, turn to [return_home].
# deep_forest
You venture deeper into the forest. The path ahead is shrouded
in darkness, and the sounds of unknown creatures echo through
the trees.
To explore the dark path, turn to [dark_path].
To turn back and return to the crossroads, turn to [return_crossroads].
… and so on
