The game also introduced several advancements that were not present in the earlier releases of this franchise, most notably the addition of “ Home City” and a “ Politician System” that can grant bonuses when certain goals are met. In this game, the ages include Discovery Age, Colonial Age, Fortress Age, Industrial Age, and finally Imperial Age that unlocks access to all buildings, upgrades, and defensive/offensive military units. Set in the age of the exploration of the Americas, the core offering of this game is centered on the eight civilizations (British, Spanish, French, Portuguese, Russian, Dutch, German and Ottoman) that move through the five distinct “ages” and all unlock access to more capable home base buildings and military units. Immediately after launch, the Age of Empires 3 for macOS managed to become one of the bestselling Mac games of its time, reaching over 2 million gamers in its first three years on the market. After two celebrated games and their expansions who focused their visual style on showcasing hundreds and thousands of 2D Sprite-based units, the third game of this franchise moved completely to 3D visuals that were first introduced by the studio in their popular Age of Mythology release from 2002. Age of Empires 3 for Mac (also known as Age of Empires III) is a popular real-time strategy developed by Ensemble Studios and published by Microsoft Game Studios on home Mac in 2005.
