Some minor changes from the board game rules were made to make the game faster to play:
- The Trade Event was replaced by an additional Civil War Event
- Players are limited to 2 fleets per ocean
- The Incas and Aztecs in Epoch VI may expand from either Capitol with 2 units
- The Automatic Retreat option was added
- The Auto-Select Empires option was added
- The Sumerians have been restored to their rightful place as a full fledged Empire rather than a neutral Minor Empire.
