Examples of modified rules from Antike:
Modular layout - when a player founds a city, he chooses whether it produces Iron, Marble, or Gold
Over 20 event cards, which provide more variety in the game
Town walls for individual protection of cities
Each "Know-How" costs a different amount - for example, inventing the market is more expensive than inventing the wheel
A new Know-How for trading goods with the bank
Higher costs for legions and galleys - they are first recruited from the bank to the personal supply (paying gold)
Easier rules for conquering cities with no movement of units
