I mean I liked Watch Dogs(after the first act) I took me a while to really get into it, but once I did, I couldn't put it down. I've heard Killzone is decent, but its probably more multiplayer focused. Also, Tomb Raider: DE. I played it on PS3 and loved so I can only imagine its just as good on PS4.
As for future releases, AC: Unity, Shadows of Mordor, Far Cry 4.
2015 will be crowded
