I'm no expert, but I guess it's because some individuals don't want to be recognized as either sex.
That's not quite accurate - see https://www.merriam-webster.com/dictionary/they however more to the point, we don't live during Shakespeare's times. You could have cited (as per what I linked) other literary sources, in various contexts, for the use of plural pronouns applied to singular persons, however those were in formal or literary contexts.
So- several would likely seem very quaint to most people today. Not that I object in any way to someone who sees themselves as nonbinary, it's the context that you've tried to apply.
Canon pronouns real? Let's goooo
Goofs aside, not everyone likes they/them pronouns, so it would probably cause a fuss. Maybe one day, if someone feels like its worth the bill to now record another set of alternate takes.
would be weird for the german version. they would either have to use english pronouns which would probably offset a lot more people or use 'it'... would be funny to see the reaction of the people who demanded this only to read 'it' in the end xD
If we are to believe that the individuals so desperate to see this implemented consider it to be important then they should, in turn, recognise that many of us consider the pronouns in use already to be something we do not wish to see replaced or eroded away entirely.
There would be far less opposition to this stuff if it came as something implemented as a third option that players could pick if they so desired.
The game is also a decade old and some of the voice actors are either retired or sadly deceased - so going back and reworking things isn't entirely viable. Suddenly adding the option in a future expansion would simply be jarring, since it would be exceedingly clinical for the Scions who have supposedly become the player character's close friends and adventuring companions to switch to more distant pronouns that lack a personal touch.
I'd prefer feminine pronouns for my character, I wouldn't mind a gender neutral option or any option to set your pronouns.
I know this is likely a bait thread, but I've got a couple nb characters, so this option would be wonderful!
