Sometimes! I like League of Legends and it's really popular in Korea, so I'd love to watch it in Korean. However, usually you need a Korean social security # to sign up for websites that stream the game :( But I changed my videogame to be in Korean text and audio hehe

I love watching people play video games in my target language. I use this method a lot to practice German. Bruugar and Gronkh are my favorites, since I find them easiest to understand.

I want to find someone I can watch who does commentary in Cantonese. Unfortunately I'm having trouble finding anyone who does this. If anyone knows of someone who does, I'd love to hear about it!

@Aslihan yes I know some but they do I lot of cussing in their gameplays dashiegames and the radbrad.

I've done it for German and I think it helps. The language is rarely too complex and it's usually easy to guess the meaning from the context.

This channel has a lot of videos of them playing video games in English: http://m.youtube.com/user/LetsPlay

I tried in English for improving it and i started with pewdiepie (who isn't a native english speaker -_-). It helped me a lot though. Before that i was just able to understand the basics. And now i can even get the jokes, that means a lot to me.
By the way i don't know much youtubers who play games, can you suggest me some ^^
