For nearly a decade, the "Forza Motorsport" franchise has been the premier racing series for Xbox fans all over the world. The first "Forza Motorsport" game launched in 2005 and was immediately one of the must-have games for the Xbox. The same was true of the "Forza" games that launched for the Xbox 360 in the following years, as the series quickly solidified its place in the racing game pantheon.
Naturally, "Forza Motorsport 5" for Xbox One was no exception, as the game was lauded by critics and consumers alike as the best-looking and most realistic racing game of this or any other generation. Perhaps not surprisingly given its lofty status as the Xbox One's first killer app, today Turn 10 Studios announced that "Forza Motorsport 5" has been embraced by Xbox One fans worldwide, with more than one-third of console owners purchasing the game since its November 22 launch. This makes it the best-selling racing game by console attach over the past decade1.
