Not that I'm advocating Mahjong, because I don't really know how to play it, but which is worse, 200 variations of that, or the 20,000 different cards games that seem to be out there that most people have either never heard of, or never care about. I mean, how many of those "1000 different card games for windows" cd's can Wal-Mart scrounge up in a year!?!
At least the Japanese make it interesting sometimes by giving you a picture of a naked chick if you clear the board. Anybody even wanna think about what you'd get if you were to play old maid under the same premise!?
