Accordng to IGN, the NPD numbers for December hold more worth than just comparing figures for hardware and software sales in the U.S. during that month (or fueling fanboy debate). December's numbers show that the Wii enjoyed a tie ratio of 8:1, meaning that for every console sold, around 8 titles went along with it. Impressive.Considering the top titles for the month were Super Mario Galaxy, Wii Play and Sonic & Mario at the Olympics, it's a safe bet that copies of them went off the shelves with the consoles. Of course, this isn't meant to be taken as a literal statistic, as should 7 individuals walk into a store and pick up a copy of Super Mario Galaxy and 1 individual buys a console with the game, the statistic would still hold true.
