Playstation Plus is required for PS4 online game play. It also offers FREE Games on a monthly basis for PS4. These games never expire as long as you keep your membership. The longer you have your membership the more games you will accumulate. We have had this membership since the launch and we have compiled hundreds upon hundreds of games across all Sony consoles. We feel that this membership is a necessity and is now vital to access all features of the Playstation 4.
