You're probably thinking of SEAsia where a city like Angkor Watt was just one giant temple+palace and everything around it was simple wooden houses because the caste system didn't allow people to live in something fancier than their status allows.
Mesoamericans weren't like that. They had a decent amount of urban infrastructure to their cities and the game tries to reflect it. A city like Tenochtitlan (Aztec capital) was basically something you'd expect to see in ancient Babylon crossed with Venice, Teotihuacan (older than the Aztecs, but they incorporated it and lived there as well) was basically pure Mesopotamia with pyramids.
Mayans (more tropical and less centralised/unified than the Aztecs, Zapotecs and others from a little further inland and away from the Carribean shores) were closer to the SEAsian example in that they had a highly stratified society with actual nobility (to get ahead as an Aztec, all you needed was to win some slaves). They still had intricacy to their city core where said aristocracy lived and ceremonies were held but once you were past that, it was basically just lots of village units close together.
Mesoanon can surely do a better job explaining the mechanics behind it but it should suffice as a sort of TL;DR.
