It's really a toss up between 2 and 4 for me. 2 had an amazing story and took things to another level at the time. But 4's story is great too and I love how the game really comes full circle. They really did a brilliant job.

Forgot the Vita game! BTW it is a OK but no UC2 UC4 is good, I really enjoyed 2, will not vote until I have done the last 20% of 4, someone bump this so I can vote on Wednesday

Uncharted 4 is on my greatest games of all time list.
