Of the 20 best-selling PC games at U.S. retailers in December 2008, 7 of them were within The Sims franchise. If you bring Spore and its parts pack into the equation, that means Maxis-helmed games accounted for almost half of the month's top sellers.

And let's not forget that The Sims 3 is due out February 20. Anyone want to bet how long that'll be at the top of the sales charts? Weeks? Months? Years? Decades?
