According to Wikipedia, FWIW, 1.5 billion people speak English as a first or second language. That means there is a significant language barrier for ~78% of the world.

> in Europe it's not like we have to learn something totally different (like Chinese is to English)
Imagine how English is for the 1 billion people in China!
I wonder how many people are fluent in languages using the Latin alphabet, or speak any Indo-European language.
As I argued, that's not exactly true. As long as your mother tongue is not something totally different, you do not have to qualify as an English speaker to learn how to program. It's the same with games: Sure, kids don't know how to pronounce "Game over", but they know what it means.
I started programming at around 13 years old when I have had English classes for 2 or 3 years (since 5th grade) and did not have any problems. My biggest problem was the IE 6 box model, really, and that for a while I had a hard time abstracting the "a class is a car and this object is a BMW car" to things I actually could needed. I have to say, though, that I used German language books and forums for help back then before Stackoverflow was a thing.
