Age of Empires II has a particular strength: its "standard game." A number of variables may be set by the user or left to random selection (such as nationality and geography). This provides a nearly limitless combination of foes, allies, and landscapes on which to play. Each of the approximately 15 nationalities has unique abilities - imagine Starcraft with 15 alien races instead of 3. Turtling is limited by the trebuchet - a huge catapult - and cannons. If you get the game you will want the expansion as it allows more automated farming and provides new races such as the Aztec. MS is on the right track with this very impressive game.
