The system has finally accumulated enough games to warrant a purchase if you only play exclusives. My rule(which I also applied on Wii U) is to wait until there's at least 6-8 games I want on the system before buying it.
Exclusives like
-Uncharted 4
-Bloodborne & Old Hunters
-Ratchet & Clank
-inFamous SS
-Driveclub & Driveclub Bikes
-Until Dawn
-Tearaway Unfolded
-Resogun
-Alienation
-Disgaea 5
-Killzone Shadow Fall
-The Order 1886 (as a visual spectacle, see how far real time graphics can go)
With some nice console exclusives:
-No Man's Sky
-Guilty Gear Xrd
-Street Fighter 5
-The Witness
-Firewatch
-FFXIV
-SOMA
-Tales Principle
Exclusive/console exclusive indies like:
-Salt & Sanctuary
-Transistor
-Helldivers
Japanese games:
-all of them
With an amazing outlook for the next 6 to 10 months with heavy hitters like Nioh, Horizon, Persona 5, The Last Guardian, GT Sport, Gravity Rush 2, King of Fighters XIV, God of War 4, best version of FFXV, tons of other smaller and Japanese exclusives possibly all coming out, you will never have any problem with droughts.
To me PS4 was worth it from day 1 as I also play multiplats on it, but if you're only into exclusives then u might consider buying one now, the killer apps are here.
