Thanks for the link. It kinda proves my point: since the release of the PS4 and the fact that the PS+ is now mandatory to play online it is not as necessary as before to have a convincing offering of games to make people subscribe to the service.Here's a solid list for NA that sadly ends in January of this year.

On PS3, 47 retail games and 81 psn games.
On ps4, 1 retail game and 53 psn games.
You can easily see why the amount of retail games decreased: average value per ps3 retail game is 31$ and average value per ps4 psn game is 16$.
In addition, you can see that the average score of the games offered decreased: 82 for a ps3 retail game, 77 for a ps3 psn game and 73 for a ps4 psn game.(toythatkills that's for you)
