Citadelum is a city builder set in legendary Ancient Rome. Build your own settlement, gather resources and evolve it into a magnificent city. Explore the world, trade and lead your mighty legions in epic tactical battles. Earn the favor of the Gods or challenge them, if you dare.
Players start by constructing basic infrastructure like housing, food production, and water supplies. As the city grows, players must expand and streamline production chains, building specialized workshops and service buildings to meet the needs of the population. The game uses an intuitive zonal system where buildings automatically service the surrounding area, making managing supply chains and resource distribution more straightforward than earlier city builders. Players must carefully balance the needs of the lower-class plebeians and wealthier patricians, providing adequate housing, food, religion, and entertainment for both classes. Upgrading residential buildings and adding decorative elements increases the city's prestige, unlocking new upgrades and building types.
Beyond the city limits, the game features a strategic world map that players can explore and expand into. This allows them to open trade routes, gather resources, and confront enemy forces in tactical auto-battles. The world map adds an extra layer of strategy, as players must carefully manage their military and economic priorities.
A unique aspect of the game is the central role played by the gods of the Roman pantheon. Players can curry favor with these deities through offerings and sacrifices, granting boons and protection for their city. Conversely, angering the gods can lead to divine punishments, such as natural disasters or direct divine intervention. Managing the relationship with the gods adds an unpredictable and dynamic element to the gameplay, as players must balance appeasing different gods while avoiding the wrath of others.
The game is praised for streamlining many of the classic city-building mechanics, making it more accessible and user-friendly for modern audiences. Features like the intuitive zonal building system, automatic resource distribution, and clear UI help reduce the micromanagement burden, allowing players to focus on higher-level strategic decisions. While some veteran players may find the reduced complexity disappointing, many reviewers appreciate the game's more streamlined approach as a way to capture the essence of the genre without becoming overly burdensome.
