New Civilization 3 Guide

Ages: The game is divided into the Antiquity Age, Exploration Age, and Modern Age. Each age has unique tech and civic trees.

Civilization Transitions: Each civilization is bound to one age. Based on player actions and choices, leaders can transform their civilization for the next Age (e.g., Rome in Antiquity can become Normans in Exploration, then French Empire in Modern). Civilization choices are influenced by the leader, previous civilization, and specific gameplay elements (e.g., owning 3 Horse Resources grants access to Mongolia in the Exploration Age).

Crisis: All players face a temporary 'Crisis' during each Age shift, requiring the addition of negative policies. This mechanic aims to balance the game, preventing runaway leaders or insurmountable deficits for trailing players.

Influence Yield: A new yield type, 'Influence,' is introduced and used for diplomacy with other civilizations.

Rivers: Rivers are now categorized into small rivers (crossable normally) and wide, navigable rivers. Navigable rivers allow Naval Units and embarked Units to travel through them. Both types of rivers now run through tiles rather than along their edges.

Settlements: Settlements are divided into 'Towns' and 'Cities,' both categorized as 'Settlements.' Except for the Capital, all Settlements start as Towns, which cannot produce anything on their own (all Production converts to Gold) but accrue yields and allow for the purchase of Buildings. Towns can eventually be upgraded into Cities.

City Naming: City names are now rendered in their civilizations' native languages.

Settlement Age Limits: Settlements are limited by Age based on estimated numbers.

Settler Units: Settlers are divided into two units: the 'Founder' (a Civilian Unit) and the 'Settler' (which produces the player's Capital).
