So basically this means no buying used games, no renting PS3 games, and no sharing PS3 games with your friends.Originally posted by ikachii at IGN
"SCE has secured the patent for a new disc technology that, if used, would not allow the PS3 to read used games for that platform. The technology was invented by Kutaragi himself, as well as two others
Details regarding the patent are featured here: http://www.ipdl.ncipi.go.jp/homepg.ipdl
It is indicated specifically that the technology is to prevent the use of used as well as pirated software
The technology involves actually rendering a authentication code originally encrypted on the game disk unreadable to other machines once the disk it is used
This would mean that Net-based and other such games will not be the only ones to be affected by the technology
Naturally third software developers would embrace this technology, and it would ensure sales of the inevitable "Best series" for the PS3, but used games shops would be put out of business if the PS3 were to become the primary platform in the next generation
While information regarding the patent does not specify outright that the technology will be used in the PS3, Kutaragi has gone on record saying that copy management is absolutely necessary in order to endure that no "Napsters" of the game industry create problems in the future "
