Sony patents degradable demo

A new patent filed by Sony may change the way users play a videogame demo, literally.

The idea, known as the ‘degradable’ or ‘deteriorating’ demo would allow users free access to a full game, only to have the features of the game removed over time. Possible features that would be removed include weapons, playable characters and levels. The patent is also said to involve changing sound effects and adjusting brightness as a means of encouraging the user to purchase the full game.

According to Siliconera, the patent boasts it is preferable to the current system of demos because the technology could be distributed on physical media. A digital code for the full game would be the only thing needed in order to restore the game back to its intended state.
