As the console wars continue to run at their usual breakneck pace, rumours are flying that Sony's soon to be announced console and the next Xbox will both refuse to play nice with second hand games. Should these rumours prove to be true, it would appear that both Sony and Microsoft are planning to release content protection systems that could all but render second hand games unplayable.
Sony filed a Patent (US20130007892) in September which is understood to still be awaiting approval from the US Patent Office. If approved, shutting down the second hand games market makes a lot of sense for Sony and game publishers, both of whom most likely see second hand game sales as a major source of lost revenues.
Under Sony's patent, each games disc will have an embedded RFID chip (much like what is used by clothing stores to deter shoplifting) which would wirelessly communicate with the games console. This would see game discs storing information about which console they've been wireless paired with, rendering them unplayable on other consoles. Under this new regime, second hand games would quickly become useful only as drink coasters.
Alternatively the technology could also see the console requesting a fee to unlock the game, or even specific portions of the content (for a free trial for instance). Another side benefit of this system for Sony is that it the technology would also make games extremely difficult to copy as pirates would have to get hold of RFID embedded optical discs.
The rumour mill is also starting to go into overdrive around the next Xbox, and it looks like Microsoft's next version of the Xbox console could also have it in for second hand games. Where Sony have opted for proprietary media, the rumour mill has it that Microsoft appear to be adopting the simpler (but secure) method of requiring an internet connection and activation codes for games that are said to be on 50GB-capacity Blu-ray discs. Based on this it appears that second hand games will not be playable.
