Wood, Food, Iron and Stone in the demo

Harvest & Mine replaced gold with Wood, Food, Iron and Stone. The developer identifies Sawmills, Quarries, Mines and Windmills as the resource buildings supporting this economy. Old advice built around Meadhall gold income belongs to an earlier system. Read the July economy announcement.

For an exact purchase, use the requirements shown in your game, and do not assume one resource can substitute for another.

1. Building blocked? Check resources and island space

Choose one immediate project: improve a weak defense, prepare an island attack, or increase production. Write down its required materials and compare them with your available stock.

An unavailable purchase can have different causes. Check the condition before investing in more production:

Symptom What to inspect Next decision and observation
A displayed material requirement exceeds your stock Compare each of the four resource totals with the full cost Address the missing material; check whether that requirement is met before adding unrelated production
The costs appear affordable, but the island has no building room Inspect the island's building capacity and the placement feedback Find an eligible location or plan additional territory; a larger stockpile alone will not create a plot
The intended tower or upgrade is not available Read its unlock requirements and the relevant progression description Establish which unlock is missing before treating this as a resource problem
A production upgrade appears to have little effect Read the affected building/resource and the benefit's conditions Confirm it applies to the production you actually use; compare displayed output where available, without assuming a collection interval

Island building capacity was introduced in New Heights. This is why space belongs in an economy decision alongside materials. Unlock types are covered in the skill-tree guide.

For example, if a tower's cost panel shows a Stone shortfall while Wood is plentiful, another investment aimed only at Wood leaves that immediate requirement unresolved. Compare an accessible source of the missing material, an expansion that could provide it, and a smaller defensive purchase you can already fund. Use the requirement shown in your run, rather than assuming all towers have that cost.

2. Where to place resource buildings

The August balancing update says global production bonuses apply to a resource building's total output, including contributions from adjacent resource spots. That makes placement relevant to how much a production upgrade can help. Read the 17 August economy changes.

If the current interface explicitly shows a candidate site's production contribution, compare it with what you already have. Otherwise, use the visible resource spots and the building's description without inventing a numerical preview. A larger useful production base could, in principle, gain more from the same percentage bonus.

Do not count a distant opportunity as free income. Include the resources and attention needed to reach it, contest it and use it. A smaller improvement within your current position may fit an urgent need better.

3. Expansion vs defense: keep a reserve

Make the defense reserve concrete. Identify the defensive purchase or upgrade you would want available if the next engagement exposes a weakness, then keep the required materials out of the expansion budget.

Avoid using a universal reserve percentage: different purchases can require different combinations of resources. The useful reserve is one that funds a specific response.

When comparing expansion options, consider the position you would have after paying, not just whether you can afford the first step. If the project depends on everything going perfectly, reconsider its scope.

4. Trace the first cause of an economic collapse

In an October discussion, a player described losing resource territory and then lacking both funds and building room to recover. It is a useful failure pattern to investigate, although one report does not establish every current limit. Read the player's account.

During your review, distinguish the initial loss from its consequences. Did you overcommit to an attack, spend the recovery budget, or depend on a position you could not hold? Buying another production building next time will not necessarily fix the decision that exposed the first one.

If a balance or output looks wrong, compare the current requirement, resource display and building description before assuming a bug. Do not infer collection intervals or worker rules from other strategy games.

Continue with defense and expansion priorities or how skill-tree unlocks affect future options.
