The fourth title in the franchise, Uncharted 4: A Thief’s End, came out five years after the third game, in 2016. That would mean he was around 35 in the third game. Nathan Drake’s Age In The Four Uncharted GamesLet’s assume he was 15 upon meeting Sully, making Nate’s birth year 1976.
With that being said, the third game makes it clear that Nate is somewhere in his mid-thirties, making it easy to infer what his age likely was in the other Uncharted games. Here's how that looks on a timeline:It’s completely possible that Nathan Drake may be a year or two younger, particularly if he meant he was in jail at age 15 and met Sully at age 14. This would also make Drake 44 years old in the year 2020, if he was born in 1976, that is. Then, when the second game, Uncharted 2: Among Thieves, released in 2009, Nate would’ve been around 33 years old. Similarly, if his birth year is 1976, then he would’ve been approximately 31 when the first game, Uncharted: Drake’s Fortune, released in 2007.
