Factory Resources in Civilization VII are a new gameplay mechanic introduced in the Modern Age, designed to enhance the strategic depth and economic management of your civilization. Here's a detailed breakdown based on available information:
Overview:
•Introduction: Factory Resources become available upon reaching the Modern Age, following the Antiquity and Exploration Ages. They represent a shift from traditional resources to more industrialized, specialized resources.
•Function: They provide empire-wide bonuses when placed in settlements that have a factory. Unlike previous resources, which might have been limited to local effects, Factory Resources can offer widespread benefits like increased production, science, or culture.
How to Use Factory Resources:
•Research Requirement: To unlock Factory Resources, you must research the Industrialization Technology. This is followed by Mass Production Technology, which allows you to construct Factories.
•Building Requirements: Rail Station: You need to connect your settlements to your capital via railroads. This means constructing a Rail Station in both your capital and the settlement where you want to build a Factory. Railroads are unlocked by researching Industrialization.
•Factory Construction: Once you have the necessary technologies and infrastructure (rail connections), you can build a Factory in any settlement connected by railroad to your capital. Each Factory can house one type of Factory Resource.
•Resource Allocation: After building a Factory, you can access the Resource Management menu to assign Factory Resources. These resources can only be slotted into settlements that have a Factory. You select from available Factory Resources and allocate them to your settlements for bonuses.
Benefits:
•Empire-Wide Effects: Factory Resources provide benefits that affect your entire civilization once assigned. Examples include:
▪+3% Science yield increase.
▪+5% Settlement Growth Rate.
▪Extra Production towards training land units.
•Specialization: Settlements can specialize in producing certain Factory Resources, which can align with your civilization's strategy, whether it's for military, cultural, or scientific advancement.
Strategic Considerations: 
•Legacy Paths: Utilizing Factory Resources effectively contributes to the Railroad Tycoon Legacy Path, providing additional points towards achieving objectives in the Modern Age.
•Placement Strategy: Since only one Factory Resource can be allocated per settlement, planning which resources go where based on your civilization's needs is crucial.
•Trade and Expansion: Factories in distant lands or islands require ports to continue trading via railroads or by sea, ensuring you can leverage resources even in geographically isolated settlements.
Common Challenges:
•Connection Issues: Ensuring all settlements are properly connected via railroads can be challenging, especially on maps with natural barriers like oceans or mountains.
•Resource Management: Balancing which resources to assign where to maximize your civilization's growth and military strength.
Factory Resources in Civilization VII enrich the late-game experience by requiring players to adapt to new economic and strategic challenges, emphasizing the importance of industrial development and connectivity in the Modern Age.
