TL;DR
Add font so that dyslexic and dyscalculia people (and others) have an easier time reading all the text in the game.What?
A way or method to more easily change the font that the game uses everywhere.Specifically a per player option to change the fonts.
Here is OpenDyslexic in the main menu as an example for how it can look;
Why?
A lot of the text is made in the same style, one that for some people with some forms of dyslexia and dyscalculia is headache inducing to read.A friend that tried factorio even stopped because of said headache.
For her this specific font would help her, ([which is why it is now a mod on the portal](https://mods.factorio.com/mod/OpenDyslexic_font)) and by applying logic I assume that for other people different font would help besides just the scaling in the text.
