What's a CYOA? Not the "turn to page 47" gamebooks. On /r/makeyourchoice, a CYOA is kind of a character creation screen for a game that doesn't exist. You get some points, pick powers and drawbacks from a menu, and try to build something cool.
Half the fun is minmaxing or creating a build that tells a story. Take a drawback you can live with to afford something good. Find combos the author didn't think of. Then post your build and explain what the world would be like and what you would do.
Quick small CYOAs.
Build your abilities from a menu of options.
Character creation through narrative. Your choices shape a story.
