Stale, Even Then
Age of Empires II was an obsolete RTS that failed to match the brilliance of other RTSes of its day, such as StarCraft. This expansion, released a number of years later, does little to fix it. There is still no attack-move command, and while the addition of new civilizations and units can be fun (the turtle ship especially), there is no flavor to the additions. Koreans play like Japanese play like Turks; the only difference is a handful of units in each civilization. Let's not even talk balance.
