Heh. I'm sure there're people sufficiently-into mahjong. The scanlations I saw were quite competently-done.
So it's possible! Just have hope.
Besides, it's just like anime to make something that seems ._. complex become interesting and fun...I personally liked Hikaru no Go, but I still have no idea how to play. Doesn't mean I don't enjoy watching how they play, though! XD
