Discussion: Incas unique architecture

Hi

Do you thinks the Incas needs an unique architecture style, like the Indians? I mean, both Aztecs and Mayas are located in central america, but Incas in South America from Ecuador to central Chile. IMO, buildings like the monastery and the university didn't fit with the inca architecture. The style should be named "Andinean architecture".

Which another civ deserves a unique architecture style? Japanese maybe?
