Which game was bundled with the Xbox 360 Kinect and became its best-selling title?

Kinect Adventures! was bundled with the Xbox 360 Kinect and became its best-selling title.

The game was developed by Good Science Studio and published by Microsoft Game Studios in 2010. It was designed to introduce players to Kinect’s controller-free motion tracking through simple activities such as rafting, obstacle courses, and space-themed games.

Kinect Adventures! benefited enormously from being included with Kinect hardware. More than 24 million copies were reported as sold, although that figure reflects the game’s widespread bundling rather than only individual software purchases. This makes it different from traditional best-selling Xbox games such as Halo 3 or Minecraft.

Kinect was launched as an Xbox 360 accessory in November 2010. It used cameras and microphones to track body movement and voice commands, allowing players to interact without a conventional controller. Kinect Adventures! served as the pack-in demonstration for that technology.
