why is there no spanish localization?

[CKNovel]

I have been told there are laws in France and Germany that require them to be available in the language to be officially sold there.

Also, while Spanish is spoken predominantly across the world, I imagine their market research showed it wasn't financially worth the expense to localize the game in Spanish.

Just my assumptions.

Nah, there has been many games untranslated since the term "Video game" exists.
How would you deal with untranslated mobile game nowadays, many are english only.
Plus there actually is voice acting in german and french. However for EU game many used to had English, German, French, Spanish and Italian languages.

I guess it's because of the gaming community main languages, they probably went for the most profitable markets.

EDIT: And there is way too much text in-game to consider translating it now.
