They can't spell because they're thick!
RA3 was great for single player but its a simple gamers RTS, its not aimed at hardcore Cossacks fans like me who like no rush time, resource management and huge battles. The casual gamer / masses can't cope with gathering more than 1 resource (Cossacks has 6, AoE has 3), economic management etc.
When it comes to multiplayer Age of Empires 3: Asian Dynasties has been the best RTS ever made to date. Nothing has the same level of quality of graphics, interface, variety of units / nations and balance.
