Well, the main hurdle was that we were 7-9 years old iirc and didn't know any English at all, beyond the memorized "knock knock" etc. So the topic of the questions wasn't on the table :-)
I did this but inverted. When only pokemon red/blue were out in the US I downloaded a rom for pokemon yellow (discovered on whatever p2p I was using at the time) when searching for pokemon to play in an emulator. I didn't know it existed at the time and it was in Japanese. When I told my friends "pikachu follows you around!" None of them believed me.
