I'm looking into a ps4 at the moment, has anybody got any 'essential' games they think I should get with it?
People have listed a fair few already that will get you started like The Last of Us, Dragon Age etc for good single player experience.
Then for multiplayer you can't go wrong with Destiny / CoD / Fifa.
Also keep an eye on the free games you get with the PSNetwork. Picked up Binding of Isaac for free and that kept me going for a while. Still need to check what free games are out this month actually! Last month was a bit poor.
