Pro Wide selection of missions
Players will see many different missions ranging from rescue missions to defensive missions. What is even better is that many of these types of missions will be mixed together into one, so there is a varying structure to each making for a different feeling to each.
Pro Graphics-gameplay balance
It is difficult to find good real time strategy games with aesthetics. Its high resolution graphics combined with fairly good RTS experience makes Age of Empires III a rare gem. Its AI and gameplay may not be up to the mark when compared to its predecessor, but still provides you a fair challenge.
Pro Card-based upgrades and reinforcements add more to each match
Age of Empires III features a new and unique card-based system that allows for you to deploy additional units and resources from your Town Hall. By eliminating enemy units and buildings, you are awarded experience, which not only goes toward your City Level (allowing you to purchase more cards out-of-match), but allows you to activate a card in-game. These cards can grant you additional soldiers, increase gathering speed of Banks and Workers, or even a fort that you can deploy anywhere in the map.
Con Easily manipulated AI
During AI skirmishes, you can easily fortify your location with walls, cannon towers, and forts, ensuring that the AI continually sends large armies to their deaths. The AI will also only send their units to one certain spot of your base, thus you will always know where they will come from and which portion to build defenses at. Once your base is fortified enough, you can simply farm for experience, until no more can be gained, and then easily wipe your AI opponent out, making for one-note style of play
