On a gameplay front, Uncharted 2 is a high on my list. Just going for something memorable I have to say that I found The Last Guardian striking despite having to fight the game mechanics a lot. Gravity Rush I also enjoyed a lot because of how "not-safe" as a franchise it was against mostly everything else that Sony does. Refreshing.
Worst I'd say Ratchet & Clank 2016 on PS4, what a steaming load of generic shite. Zero personality, zero fun. Uncharted 3 feels a bit weird and unnecessary (and weirdly, full of awesome set pieces, but manages to be less than the sum of it's parts), but I wouldn't say bad, aimless at parts perhaps.
