The Civ games tend to share identical concepts, though sometimes they are referred to by different names. Differences between units will not be listed here except for very basic types common to all games. SMAC has the most different terminology, being an unofficial Civ game (although designed in part by Sid Meier) and being set in the future on another planet. For differences in terminology among the Test of Time games, consult the manual. Freeciv always uses the Civ2 term.
Warning: This may not be accurate yet, and does not include Call to Power terms.

- In Civilization 1 and Civilization 2, Settlers function both as city-building units and terrain-enhancing units. If we were to follow Civ1 terminology here, the word "Settler" would create ambiguity for Civilization 3 and SMAC players. Therefore, the Civilization 3 terminology for "Settlers" and "Workers" has been adopted as an exception to the general rule to use Civilization 1 terminology. Civilization 1 and Civilization 2 players can simply read both words as "Settlers".
- The word "village" is synonymous with Minor Tribe. They are invariably called "goodie huts" by fans, because they usually dispense "good" things such as free technologies or money and in most graphics sets they are represented by a hut (or small number of huts). "Goodie hut" is often abbreviated to "hut".
