I am NOT an "English speaker". Excellent diction by the way, lol... Can you not even read?

Sure. I read that. But I don't see how it's relevant to my point. I explained that it's not easy for everyone to learn English.
It's great that you've taken the time to learn a second language. It's also quite clear that Kirk187 has so far learned some basic English. But just because some of us have the opportunity to learn English for one reason or another, it doesn't mean we should be arrogant and act like it's easy for everyone.
(translations, voice-overs, localisations in general cost too much, take too much time [even if you can afford them] and worse of all, restrict too much. Less things you can alter willy-nilly, less freedom to do 'last minute' additions, exponentially larger QA testing periods, meaning longer waits for patches, as each and every game version needs be run separately. Why? Because self entitlement, the plague of this century. They can't even learn English ffs, the universal language..)
Kirk187 specifically asked for subtitles. Who said anything about localised voices?
There are 203M (first language) Portuguese-speakers. This is compared to about 335M (first language) English-speakers. You expect all of those Portuguese to learn English just because you could do it?
It's ironic that you accuse me of being entitled, when my entire message was expressing humility about the fact that I have it easy as a native English-speaker. I'm not asking for anything for myself. English suits me fine, but it doesn't suit all of my friends.
The fact is that 203M Portuguese is a massive potential market. I don't know how easy it would be to market to these major language groups, but if Larian can work out the marketing, there's certainly massive potential for return on investment by making translations for 1,197M Chinese, 260M Hindi, 237M Arabic and 203M Portuguese. Compare this to some of the languages catered for in the original D:OS such as the 80M French and 92M German (especially considering that more than 25% of French and more than 50% of Germans already speak English!).
No matter how you look at it, Chinese is a bigger language than English. The "English is a lingua franca" argument utterly falls flat here. "Internationally", English is the world's lingua franca. However, this relies on dismissing China as a single country, and forgetting that internally China is just as big and as culturally diverse (and more populous) as all of the countries in Europe put together.
English may not be your first language, but from your arrogance it definitely sounds like you're speaking from a western background.
