Is The City of Lost Gods.... Inca or Aztec?

By Matt Holmes / June 25, 2011

What is the difference between Inca and Aztec? Is their a difference? That probably sounds like such an ignorant comment but neither are time periods I'm familiar with, but am I right in saying that the architecture was similar?

Slash Film have been sent a photograph from the floor of the Comic-Con from what looks to be the booth of Indiana Jones and the City of Lost Gods. Is it significant for the upcoming film? Is the City of Lost Gods... something Aztec perhaps?
