What the city-and-card plan is buying
An ore-and-wheat economy can improve existing production through city upgrades. Sheep gives it another spending route through development cards. The attraction is that much of the plan can work from positions you already hold, rather than requiring a long road network before every improvement.
Its weak point is access to new terrain. An opening with no wood or brick must explain how it obtains expansion materials. “I will trade later” needs a plausible supplier or a workable bank or port exchange. A resource that everyone wants can be difficult to buy even when your hand looks rich.
What the road-and-settlement plan is buying
Wood and brick let you compete for territory, but roads only become productive when they support a useful destination or a deliberate award contest. Treat each proposed road as part of a route with a cost and a purpose. A longer network is not automatically a stronger economy.
Wheat and sheep still matter when the destination is a settlement. Imagine repeatedly collecting wood and brick while your only sheep number is weak and nobody wants to trade. You can draw lines across the board without completing the buildings that make them useful. Plan the whole expansion package.
Worked decision: a city now or a race for space?
Suppose your current ore–wheat position is productive, while a strong new corner lies two roads away and another player can reach it next turn. Upgrading a settlement may improve long-term output, but it does not preserve that corner. If the new site fixes your missing wood supply, losing it may change the entire plan.
Now remove the opponent’s competing route. The same site is less urgent, so investing in current production becomes easier to justify. The resource layout did not change; the timing did. This is why a universal claim that cities or roads should always come first is too crude for an actual decision.
Build a transition into the opening
A road-heavy opening can seek ore and wheat with its next settlement. A city-heavy opening can use a strong surplus to obtain a road package through a port. Identify that transition before the shortage becomes an emergency. You do not need equal production of everything, but you need an affordable path to what the next stage requires.
When reviewing the game, ask whether your plan had a transition and whether the board still allowed it. Separate a denied destination from a random production drought. The useful lesson is which option you should have protected, or when you should have switched—not which resource deserves to be declared universally best.
