Hi all, i am very curious and i would like to know if someone here has any idea about the popularity of AD&D in Japan:

How was the impact of the game there when it was released?

By the way, when was it released in Japan?

Are there still people playing it in that country or it has been "defeated" by third and fourth edition (as happened in the rest of the world)?
