Age of Empires makes a comeback by jumping forward to the Imperial Era. Cannons, muskets, armed cavalries, large vessels and more cannons present a change of pace from the old sword-and-shield Age of Empires II. The third instalment of the franchise also introduces trading routes, a set of locations that you have to capture and control by building trading posts on it, reinforcing your income and XP gain. You can order shipments of goods from your mainland at intervals of time and befriend local indigenous tribes.
In a sense, there are plenty of new features to keep long time fans of Age of Empires interested, while retaining the same core gameplay. Build stuff, gather stuff, advance Ages, kill baddies. Only this time, with more cannons.
