wii-sports-2 Nintendo said today that it has sold more than 1 million Wii Sports Resort games in the U.S. alone since its launch on July 26, a bright spot for a games industry that has had few big hits so far in 2009.

Wii Sports Resort is the sequel to the 2006 game that helped Nintendo’s Wii console steal the No. 1 spot in the game console business. On a worldwide basis, about 50 million copies of Wii Sports have been sold.

Game sales are down for the past five months, compared to a year ago. But Wii Sports Resort is bucking the trend: It’s one of those crossover games that appeal to both novices and veterans.

My kids have been busy spending their last summer vacation days playing the game, which has a bunch of activities where you swing the motion-sensing Wii controller to make things happen on the screen. It comes with the Wii MotionPlus, an accessory with built-in gyroscopes that let the Wii sense subtle motions such as a twist of the wrist. It enables new types of interactions such as throwing a frisbee or rowing a kayak. I love the giggles that come in the swordfighting mini game, where you use sticks to knock your opponent into the water below.

Nintendo said it has sold more than 2 million Wii MotionPlus units, which are also bundled with Electronic Arts’ Tiger Woods PGA Tour golf game. The good sales show that Nintendo is doing a good job yet again with getting a good installed base for a new accessory, much like the Wii Wheel and Wii Balance Board it launched in past years. It’s important to get these accessories out there so other developers will exploit them in future games.

For August, Wii Sports Resort should help boost the monthly U.S. game sales numbers. Other big games coming include EA’s Madden NFL 10 and Eidos’ Batman: Arkham Asylum. We’ll see if these games help push the video game business back into growth mode.http://image.com.com/gamespot/images/cne_flash/production/media_player/proteus/one/proteus2.swf
