Nova Roma Production Chains Guide
Your industries do not fail from missing resources — they fail from missing carts, clogged storehouses, and dirt roads. Learn the logistics rules, the correct chain order, and the micro-district layouts that keep goods moving.
Why does my factory keep saying 'Missing Materials' when my mines are full?
The materials exist but cannot physically arrive. Nova Roma simulates every unit traveling tile by tile: a Plebeian carries 1 unit per trip, an Ox-Cart carries 10. Check three things in order — is there a Cart Depot near the industrial zone, is the road between zones paved, and is the destination Storehouse filtered to actually accept the good (not clogged with wheat)? The workshop is usually innocent; the missing cart, full warehouse, or unpaved road earlier in the chain is the real culprit.
Which production chain should I build first?
Bread, always. It is your survival baseline — starvation triggers emigration and your labor force collapses. Second is Pottery: it is cheap, sells well at the Trade Port, and produces the Amphorae your Wine and Olive Oil chains need later. Third is Wine, which unlocks Patrician housing and real tax income. Iron comes last as an endgame investment. Rushing Wine before Pottery is stable is the most common mid-game trap — the whole chain idles without Amphorae.
How do I stop my Storehouses from filling up with the wrong goods?
Click each Storehouse and manually restrict it to specific goods — never leave one on the default 'Accept All' setting. Give each district a clear storage job: food storage near farms and homes, raw goods near extractors, finished-goods warehouses near the buildings that use them. A storehouse full of surplus wheat is functionally identical to having no storehouse at all when your smelter needs to unload iron ingots.
Where should workers live relative to production buildings?
Near them. A Forester or Stone Quarry can technically operate without nearby housing, but workers commuting from distant hovels spend half their shift walking and output bottlenecks hard. Build small residential clusters within a short walk of each industrial zone, with a Granary and water access so those workers stay fed and productive. Long commutes are a hidden tax on every chain in your city.
Why Your Industries Keep Stalling
Nova Roma does not abstract resource delivery. Every unit of clay, wood, and iron ore travels on foot or by cart, tile by tile, through your city. Clay sitting in a pit three districts away from your kilns might as well not exist. Before touching a single production chain, internalize these three logistics rules — they determine whether your factories run or sit idle.
Carry Limits Decide Everything
A standard Plebeian worker carries 1 unit per trip. An Ox-Cart carries 10. If your factory depends on workers hand-carrying materials across three districts, it will starve no matter how much raw stock exists. Position Cart Depots near industrial zones so ox-carts handle the long hauls while workers handle the last few tiles.
Fix: Cart Depots near every industrial cluster; workers only for last-mile delivery.
Road Quality Multiplies Output
Dirt roads are a temporary measure. Upgrading connections between resource hubs and your city center to Paved Stone increases walking and cart speed by roughly 40% — which directly cuts the 'Missing Materials' downtime that strangles mid-game production.
Fix: Pave the spine road between resource zones and the city center first.
Storehouse Filtering Is Not Optional
Leave a Storehouse on its default 'Accept All' setting and it fills with surplus wheat, leaving zero room for iron ingots or finished wine. Every storehouse in your city should be manually restricted to the specific goods it exists to hold.
Fix: Click every Storehouse and set a whitelist the day you build it.
The Correct Chain Build Order
The fastest path to a stable economy is a strict priority order. Each chain depends on the one before it — skip a step and the later chains stall in ways that are expensive to diagnose.
| Order | Chain | Why This Position | Key Buildings | Classic Trap |
|---|---|---|---|---|
| 1st | Bread Chain | Survival baseline. Prevents starvation and the immigration collapse that follows it. No other chain matters if your citizens are hungry. | Wheat Farm → Mill → Bakery → Granary (near homes) | Placing the granary far from residential zones — transporters walking long distances cause famine while food technically exists. |
| 2nd | Pottery Chain | Fast income and the hidden backbone of your mid-game economy: Pottery produces the Amphorae that Wine and Olive Oil require later. Let pottery fail and your entire mid-game stalls. | Clay Pit (riverbank) → Woodcutter (adjacent, for kiln fuel) → Pottery Kiln → Storehouse (filtered) | Relying on a distant logging camp for kiln fuel. Kilns need intense, constant heat — build a dedicated Woodcutter next to the Clay Pits. |
| 3rd | Wine Chain | Unlocks Patrician housing tiers and high-tax income. This is where your economy shifts from surviving to funding expansion. | Vineyard → Winery → Storehouse (wine + Amphorae) → Trade Port | Rushing Wine before Pottery is stable — you will zone Vineyards and build Wineries, then watch the chain sit idle because there are no Amphorae to bottle the product. |
| 4th | Iron Chain | Endgame investment for legions and monument construction. Enormous setup cost and logistics load — only worth it once the first three chains run themselves. | Iron Mine → Charcoal Burner → Smelter → Smithy → filtered Storehouse | Starting iron early. It consumes labor, fuel, and cart capacity that your food economy still needs. |
Deep Dive: The Pottery Chain Is Your Financial Lifeline
Pottery is the fastest production chain to set up and one of the most profitable in the early game. It requires low-tier Plebeian workers, cheap infrastructure, and sells at a strong margin through the Trade Port. More importantly, Pottery produces the Amphorae containers that Wine and Olive Oil require — a city whose pottery industry fails is a city whose entire mid-game economy stalls two hours later.
The optimal pottery layout has three rules. First, place Clay Pits on a riverbank or mudflat, as close to the water's edge as the grid allows — river proximity improves both clay access and the fertility of any adjacent farms. Second, build a dedicated Woodcutter directly next to the Clay Pits: pottery kilns need intense, constant heat, and relying on a distant logging camp near your city center is the most common reason kilns go cold. Third, place a filtered Storehouse within a few tiles that accepts only pottery and Amphorae, so finished goods never compete with wheat for shelf space.
Micro-Districts: The Layout Pattern That Fixes Everything
The practical takeaway from every logistics rule is the same: build micro-districts where raw materials, fuel, processing buildings, and filtered storage sit within a few tiles of each other. Long supply lines are the primary reason experienced players watch their industries collapse.
| District | Layout | Result |
|---|---|---|
| Pottery Micro-District | Clay Pit on riverbank → Woodcutter immediately adjacent → Pottery Kiln within a few tiles → filtered Storehouse for Amphorae and pottery | Clay travels 5 tiles instead of 50. Kiln fuel never runs dry. The whole chain fits in one screen and runs at near-100% uptime. |
| Bread Micro-District | Wheat Farm → Mill downwind → Bakery → Granary inside the residential block it serves | Bread reaches tables without cross-map cart trips. One district feeds itself; add a second district instead of stretching the first. |
| Industrial Park (Mid-Game) | Mine/Quarry → Charcoal Burner → Smelter → Cart Depot → paved road to city center | Heavy raw materials convert to dense, valuable goods at the source, so carts haul ingots instead of ore — 10x the value per trip. |
Five Habits of Cities That Never Stall
1. Pave the spine. The road between your resource zones and city center gets paved first — a 40% speed bonus on your busiest route beats any single building upgrade.
2. Filter on day one. Every Storehouse gets a goods whitelist the moment it is built. An unfiltered storehouse is a future crisis.
3. Housing follows industry. Workers living next to their workshop outproduce workers commuting across the map — build small residential clusters beside every industrial zone.
4. Trace the first missing input. When a chain breaks, do not stare at the last broken building. Walk the chain backward: the missing cart, the full warehouse, or the dry kiln fuel line is usually two steps earlier.
5. Expand in layers, not bursts. Add one chain, confirm it runs at full uptime for a season, then add the next. A city that grows in verified layers never hits the cascading logistics collapse that kills burst-grown cities.
