$1 for something as ancient as that? *Faints*
I myself has only picked up on Chinese mahjong after begging my friends to teach me how to play. Such an addictive game too as once I got the hang of things we just carried on playing for 10 hours straight.
The japanese version seems to have a lot more rules than the chinese version (making it more complicated with the amount of hands allowed) and quite a nightmare of a scoring system too...I still need to learn it myself but there's noone to teach me this time round
