I still don't have one and won't get one anytime soon. Too busy playing older games in my backlog.
But for now it seems to have a good library that appeals to me:
Digimon Story Cyber Sleuth (can also play on PSTV if I wanted to though)
Saint Seiya Soldier's Soul
Final Fantasy Type-0 HD
Omega Quintet
Tales of Zestiria
Dead Or Alive 5 Last Round
Whatever warrior games it has that I could try out
And FF XV, World of FF, Star Ocean 5, King Of Fighters XIV, Tales of Berseria, Fairy Fencer F Advent Force, Valkyria Chronicles.
That's about it for me, worth it enough. I'm still going to wait for whatever Neo is and see if its worth getting over the original PS4, although a slim model would be awesome.
