Here’s something I drew up to help me with character creation on the current game. It’s an RPG, so players will get to choose from various backgrounds. I’m not certain all of the variables I have here will make it into game, but it helps me keep track. It will also be useful to our UI designer (when we get a UI designer). They’ll be able to see what I was thinking, and come up with a much better way to represent it in the finished game.
Since the player can mix and match, I need to make sure all of these elements combine well. Functionally that means having a paragraph for each option that won’t contradict the other choices you can make. That’s the next step. 
I’m really excited about the age range we’re using. That’ll let me talk about characters in different stages of their careers and families.
And yup, there is a gender slider in there. It will have some effect on the character summaries, but not as much as you might think. Because we’re normalizing fluid gender identities in this game. Which means… the characters will treat it as normal, and rarely worthy of mention. Gender will not gate career backgrounds, family relationships, or appearance options. And everyone gets to pick the pronoun they prefer.
