I love mythology and history of Greece and Egypt etc, there are a lot of informative things on this game, so educational as well!
The addons bring a little more for the player too.
Though I've never enjoyed the low numbers of people you can have (mostly being spoilt by games such as American Conquest!) it still brings much gaming pleasure, its nice just to build too, very relaxing for the soul!
Maybe Age games will eventually rid of the population limits? But until then Mythology brings happy times ;-)
Also great for first time players, easy really does mean just that, no pressure to have to pick up the pace and rush things.
You can access info on individual units as well throughout the game just simply by clicking the unit and selecting the picture. bottom middle of task screen to see what they are good for and good against.
