Unfortunately it’s not possible in classic unless you create multiple characters with each of the different features.
I’m sure all that branching and directing would be more of a headache than it’s really worth, especially considering how much classic lacks in popularity anymore
It’s not even possible to write your own name, unless the author gives a choice command with multiple different options.
I thought of creating a character for each skin color, but yeah God knows how much branching I’d have to do. So nevermind ;-;
I might just make a template without skin color options.
If you would create, say, 3 standard characters and give the reader the choice to choose between the three, you could easily use a “gain” to remember that through the rest of the story. You’d just have to start the episode with the if/elif/else command. All you’d have to do after that is write one characters branch, then copy it to the other 2 branches and just replace the characters names
That’s the easiest way I can think of that can still be inclusive and diverse in Classic style.
