PlayStation Plus was a Premium service some years ago on PS3 and PS Vita. During a time, Sony offered a great bunch of games each month, but the magic evaporated when PS4 arrived. Sony changed the profile of games offered on PS Plus giving preference to indie productions instead of retail ordinary products.
May could be the month to befriend PS Plus again, Watch_Dogs and Tetris Ultimate could be added to the service on PS4. Evidence incoming:
Probably, Ubisoft is preparing the field to unveil Watch_Dogs 2 at E3 16 and offer Watch_Dogs 1 on PS4 as a PS title could be a smart movement to amply the user base of potential clients for the second iteration of Watch_Dogs.
Tetris is Tetris a classic like The Cure, The Godfather or AC/DC (without Axl Rose).
