Most of the NES/SNES RPGs weren't available in German or just came really late
There was a good shop in town that had a lot of import games and my parents bought a lot from them.

I think i was like 3-4 years old as we finished our first englisch RPG with a dictionary.
If i think about that today i think it was pretty insane...Games at that time weren't tubular like they are today or haven't shown the destination with a "X" on the map...
You could waste a lot of time in them with finding the next destination you had to travel to...
Oh find a cave somewhere on the map > Leave town > big ass worldmap > have fun with searching if you don't understand the game completely.

But yeah over the years my parents and me learned english.We were able to finish every RPG without any problems.
School was pretty easy...I was on a complete different level as we got English as 2nd language.Think i never had to learn anything there and finished every test with 90-100%.
In that time i started to learn Japanese cause i didn't want to waste time and in the PS1/PS2 Era there were a lot of games i wanted to play...Today im fluent in 3 useful languages.
All thanks to games and Anime.

Self taught. Since I was very young (2/3 years old) I've had contact with the english language without any kind of subtitles (in movies or series, since I lived in Venezuela and we had Direct TV and only watched US channels) or translations (in video games), so I had to force myself, with some help of my parents (but not that much, since their english skill levels weren't that much back then too) to understand it, thanks to dictionaries and associations.

Thanks to that, by the time I was 6, I could speak 3 different languages fluently.

Watching movies/tv shows in the first place, and an english class in high school for learning proper english.

My parents thought it was important for me to learn English and French. So I got exposed to lots of TV and a video games in English and French (TV at least).

The funny thing is I think most non-native English speakers, who know the language fluently, have greater mastery of the language than native speakers.

Well of course I have learned the grammar in school but majority of my vocabulary has come from English media. From games, music, tv shows and movies. Not to mention that majority of internet is englis based... You learn the language a lot easier when you are in contact with it everyday. Here we don't really dub anything. All tv shows and movies are only subtitled. Most of video games don't have even finnish subs...Only english. I would say that because of these reasons majority of Finns (especially under 40) speak pretty good english.

You can blame the stupid TV-dubbing for that! In Scandinavia we only dub all the foreign children TV-programs :D

Actually I love dubbed television, I have no need that when I watch TV once a year to read, when I want to read subs I watch anime ;P

Well if I want to do that there is internet and not TV :D

Slovene then Japanese, English and Italian are actually quite easy languages to learn (tough I never was really trying to learn italian, just did what I had to do for school)

The one plus of being a native english speaker is getting all of the tough words. Things like You're, Your, There, Their, They're. It's stupid how many alliterations of words we've got.
