Sam Drake is such a unique character that the Uncharted fans have come to love. Based off of the end of Uncharted 4: A Thief's End, we know that he and Victor Sullivan have partnered up. A whole game based off of their story after U4 would be a great way to see more of Troy Baker's character and how Sam and Sully will work together without Nathan. Thanks to Uncharted: The Lost Legacy, we know that Sam is still in the treasure hunting game.
