Why do they talk like modern people?
If the Intro of KCD2 was accurate, for example, the speech would be like this
>Henry:
>What be these words thou keep’st shouting, good Sir Hans? Methinks they be neither prayer nor curse, but somewhat betwixt the two.
>Sir Hans:
>Jesu, Henry! Thou canst not mean thou knowest not Latin? Art thou so barren of letters?
>Henry:
>Nay, my lord, I crave thy pardon. But whilst others bent their heads o’er books, I bent mine o’er turnips. I was more oft at the plough than at the page, and my schooling was in the dung-heap, not the grammar hall.
>Sir Hans:
>By Saint Jerome, that must needs be amended. I cannot with honour keep for my guard a man who knoweth not even his nominative from his ablative. ’Tis a scandal to noble company.
instead of
>Henry:
>what's that you keep yelling sir hans?
>Hans:
>Good gracious, Henry! You don't mean to tell me you don't know latin?
>Henry:
>My apologies your grace. Unfortunately I was too busy shovelling shit and picking turnips to find time for studying Latin
>Hans:
>We shall have to rectify that. I can't have an ignoramus for a personal bodyguard.
In fact, why in hell aren't medieval and fantasy video games written with early english modern dialogue at all? We have a wealth of conversations and letters recorded from the late medieval period. Just run a language model through the Decameron and The Book of Margery Kempe then run your script through it, not that hard.
