Well you could get Age of Mythology just not this version. It is a good game.
Has four races (Norse, Greeks, Egyptians and Atlanteans) each are pretty diverse with their units. EG Greek units are more powerful but cost more than the other races. It might have changed that with the Atlanteans who can make any of their units into Heroic units who.
Then each race has to choose a Major God.
Norse Major Gods - Odin, Thor and Loki
Egyptian Major Gods - Isis, Set and I think Ra
Greek Major Gods - Zeus, Hades and Poseidon
Atlantean Major Gods - Kronos, Gaia and Oranous
Then each time you advance exactly the same as in other Age of Empires games you can choose a lesser god who will grant a mythical unit, God power and upgrades to a certain group (Archers, Siege, Builders, Buildings etc).
Is quite an enjoyable campaign for the original which starts of with an Atlantean hero Arkantos who at the time of the game they use Greek units as Atlanteans were an expansion team but they go chasing a Minotaur who steals the Trident of Poseidon. Goes on for a while but allows you to use the others races as well. I would go into more detail but that would be spoiling the campaign.
The Expansion adds in a campaign that takes place after the first and you have Arkantos' son Castor basically they start to worship the Titans over the Greek Gods which pisses off the Greeks. Was another fun campaign. =)
Great now I feel like playing Age of Mythology... I would definitely recommend Age of Mythology even the older version that doesn't have the updated graphics.
