This is good news for gamers on a budget or those who frequently sell back their game's to retailers. Even though the PlayStation 4 is expected to have the majority of its games go digital, games will still be released on physical copies. This means that people looking to save a few dollars while buying games will still have a chance to do so.
It has also been discovered that Sony had filed patents for a"Electronic Content Processing System" and "Use Apparatus." While some suggested that this would lead to companies being able to track games to individuals (and thus preventing others from playing that copy), this announcement means gamers no longer have to worry about having to buy strictly new games. It is heartening to see that Sony will allow used games on its newest console, so that gamers on a budget can still enjoy discounted games.
