They need to start bringing out PS4 games to PS+ which aren't indies.
That's not going to happen anytime soon. AAA titles take years to develop and they're struggling to get them out period, they aren't going to give them away for "free". Heck most of the games coming out even now are still remakes or cross-gen. If they released a AAA title every month for the PS4 since it launched you're probably have every major PS4 game released so far and no reason to buy any games at all. What we should be getting though is quality older AAA PS3 titles though and they've done pretty well with that but this month not so much.
