in Avatar there's a scene where cataliens are tested with taming a flying creature, and then fly around floating islands.
in Skyward Sword there's a scene where students are tested with taming a flying creature, and then flying around floating islands.
at least that aspect seems similar. I mean, it could just be Nausicca with an animal serving as means for flying; floating islands from Laputa. Whatever!
the pop culture influences are another reason why the timeline stuff is dumb.
edit: to bring it back to Uncharted:
Uncharted is Romancing the Stone
Uncharted 2 is National Treasure 1
I'm hoping Uncharted 3 takes cues from The Mummy Returns
