Overview
The idea is to introduce a systemic “economy layer” that sits on top of the existing factory gameplay. Instead of only producing items for research or launching rockets, players could also produce goods for external demand, creating a more open-ended and replayable late game.
Core Concept
- Introduce demand profiles (e.g. colonies / off-world contracts), simulated stocastically or ideally with coupled dynamical systems)
- Each demand profile requests specific items at varying quantities and time intervals
- Players fulfil these demands via rocket logistics
- In return, players receive some form of currency
- Fits existing systems: The game already revolves around automation, scaling, and logistics optimisation
- Extends late game: After megabase scale is achieved, there’s currently limited structured incentive beyond just "build bigger" (yes, the factory must grow)
- Encourages diversity: Players may need to produce items they normally ignore or optimise supply chains differently
- Emergent gameplay: Dynamic demand could create interesting production bottlenecks and priorities
- Alternate production routes: Want cliff explosives before visiting Vulcanus? Ramp up your trade and purchase explosives off the black market before you can mass produce your own
- Dynamic pricing: Certain items spike in value periodically
- Contracts: e.g. "Deliver N processing units within X minutes"
- Specialised exports: Some goods require packaging or processing before export
- Economic progression: Unlock new tech, blueprints, or upgrades via economic success
- Logistics challenges: Export hubs, interplanetary trade, or throughput constraints
This system could be entirely optional first-party mod, and not interfere with the core Factorio experience. Players who prefer the current sandbox style can ignore it, while others can use it as a structured endgame.
Benefits
- Adds a clear, scalable goal beyond launching rockets
- Encourages continuous optimisation even in mature factories
- Introduces new strategic decisions without breaking core gameplay
- Provides a soft objective loop similar to how megabases currently evolve
I completely understand that systems like this could be implemented as a mod.
However, I think there are a few reasons why this would benefit from being part of the base game (or an official expansion-level feature):
- Balance: A built-in system could be tuned alongside vanilla progression to avoid trivialising existing challenges or creating dominant strategies.
- Community: One of Factorio’s strengths is that players share a common baseline. Making this part of the core (even if optional) allows for shared discussion and strategising.
- Natural progression: Doesn't galactic commerce seem like the logical goal for all of the engineer's hard work?
I am curious to hear what others think, especially around how deep or lightweight such a system could be!
