Last night, there were lots of tweets about Sony’s updated PS4 usage terms. People referred the below point listed there on Sony’s website.
7.1. You must not resell either Disc-based Software or Software Downloads, unless expressly authorised by us and, if the publisher is another company, additionally by the publisher.
While the above terms may sound like Sony will not allow people to resell their games with others, it is not the case. The terms were always like this, even for PS3 it was the same. If Sony wants to restrict used games on PS4, they would have not started a marketing campaign against Microsoft which announced the controversial DRM policy which was later dropped. I’m sure Xbox One’s usage terms will also be similar to PS4. But the fact is, Microsoft and Sony will allow people to resell their used games, etc,.
At the same time, Microsoft has once again confirmed that there are no new DRM policies for Xbox One. It just works as you find in Xbox 360 today.
