Comprising 345 (and counting!) games, D3 Publisher's Simple series has sold over 20 million units since its inception in 1998. That's a lot of cheap junk. To celebrate this remarkable milestone, D3 is rereleasing the first Simple DS game, Simple DS Vol. 1 THE Mah-jongg, at a special price of 1,480 yen ($13.39), which is quite a bit nicer than the original 2,800 yen price.

We've often lamented the lack of Simple games in the U.S., as we're in love with both the concept (low-cost games that are modest in scope) and the general quirkiness of the games. We can't think of a better celebration of a sales milestone than to expand the series worldwide.
