Pronouns?

[Iscah]

That aside I'm pretty confident it wouldn't take much work to separate pronouns from your character's model, the game already has 2 scripts for Male and Female characters. It's probably just a binary toggle, which they could just open up to players' choice during character creation

What makes you confident?

That "binary toggle" for setting male or female pronouns is the same one for setting whether the character is male or female. There isn't a separate record of what pronouns to use - and if you "open it up to players' choice" (or even add a single third option) then it stops being a binary toggle and becomes something that needs to hold more data than the simple binary on/off.

It's also just not how the script works.

It doesn't store "he/she" in some separate place and drop them into the script as required; pronouns are built into every single piece of script individually. It might be he/she, him/her, sir/madam, Master/Mistress [Forename] or it might be an entire sentence or paragraph that needs to change for a particular situation. It would be a huge undertaking to alter every single line of text to include a third option, and open choice wouldn't even be feasible.
