Can you speak Korean? Does it matter?

One of the biggest barriers for me would be understanding the language. 

It would really suck bigtime when you're lost in some alley and don't know how to get back to your place. 

I found this sketch, but I don't know how accurate it really is though. So, take with lots of salt.

 But then, if this actually works then you would know how the words are read but not know what they mean...

I think I better get my butt over at National Bookstore and get 'em english-korean dictionary...
