Expansions
- Western Expansion Map (1988): Usable with the Hartland/Trefoil and the Avalon Hill version. Extends the game board west of Italy to cover Gaul, parts of Iberia, the UK and Northwest Africa. (Note that a version of this expansion was also available for the original Hartland Trefoil version of the game)
- Trade Card Expansion (1982): Usable with the Avalon Hill version. Adds additional commodities such as timber, silver and ivory which makes it harder for players to hoard higher value trade cards which slows down game-play. Advanced Civilization includes this expansion.
- Advanced Civilization (1991): Usable with the Avalon Hill version. Contains simplified trading rules and gives every civilization the possibility to buy all civilization advances. It also adds more trading cards, civilization advances, calamities and rules for up to eight players. It contains all the cards available in the Trade Card Expansion.
- Western Expansion: Usable with the Gibsons Games edition. It comes with additional trading cards. The map slightly differs from the Avalon Hill western extension. The additional trading cards are different from the Avalon Hill Trade Card Expansion.
- Eastern Expansion Map (1995): Usable with the Hartland/Trefoil and the Avalon Hill version. Adds Persia, Sumer, Samita and Indus people and covers the areas of Persia, the westernmost parts of the Indian subcontinent and Arabia.
