One CYOA i have is something I’ve nicknamed JRPG Traitor.
In a fantasy setting that would pass very easily as a square enix product, you are one of 6 heroes branded by the gods to defeat the Overlord whom they also brand.
You got a mark for lead hero, healer, fighter(melee dps), mage, wanderer(ranged dps), and your mark, is the betrayer. The one destined to betray the heroes and side with the overlord, for whatever reason you can select and reason out yourself.
This is one of the only CYOAs I’ve made more than one run on, and I keep meaning to do a third.
