Game demo or Kinect games demo are defined as preview or demonstration of the upcoming video game which has recently released. It’s the way to present the all sides of the video game to the consumers. Demos are basically released by the game developers to help the consumer get in touch, feel the game and decide whether to buy the full version or not. It also gives the consumer an opportunity to ask the developers change, add or remove something, an opportunity to try the trial part or episode of the game before purchasing the rest part of the adventure.
Kinect game demos are considered to be playable and non-playable. Playable demos typically have the same play structure as the upcoming full game version. A non-playable demo is the gaming equivalent of the game trailer.
