Not sure if this helps, but I've played through all the Uncharted games, and I don't know her age. Unless some smart people have figured it out from some off-remarks, no-one knows.
Chloe and Elena
Chloe
*Spoiler Alert - for those of you who do not wish to know whether Chloe lives or dies in Uncharted 2: Among Thieves, do NOT read the answer below.*No, Chloe does not die in Uncharted 2.
Uncharted 2 is for boys and GIRLS! if it was just for boys, then why would they have Chloe and Elena, (2 main girls) in the game if you couldn't be them. The point is, everyone can play this because in online mode, you can be Chloe and Elena. So girls UNITE! i'm a girl and i play it.

Uncharted isn't too violent, ESRB rated it T (teen). But it might be if you're like 10 years old. If you need more information about it go to www.wikipedia.com and type in uncharted 2: among thieves.
Uncharted 2
By far uncharted 2: among thieves but uncharted 3:drakes deception is coming out 11-1-11
In graphics, storyline, and online gameplay Uncharted 2 is superior. In everything else, Uncharted 1 is better :)
In my opinion, Uncharted 2.
