Minecraft on PS4 features worlds 36 times bigger than the ones you might be used to on PS3
Available now in North America and Europe for $19.99/€18.99, Minecraft for PS4 includes all the features from the most recent Playstation 3 version, plus bigger worlds and a greater draw distance. Players with Playstation 3 Edition or Playstation 3 + Vita Edition saves are able to import their worlds to Playstation 4. However, they won't be able to transfer your saves from Playstation 4 to Playstation 3/Vita due to various technical issues. Furthermore, cross-platform play will not be possible between Playstation 3 + Vita Edition and Playstation 4 Edition.
If you've bought Playstation 3 Edition from the Playstation Network you will be able to upgrade for €3.99/$4.99. The upgrade offer will last at least one year after the release date.
