Quick answer
Progression works best when each new system is unlocked after the previous economy can carry it.
Progression Route
- Campfire phase: stabilize food, wood, stone, housing, and storage before chasing wider systems.
- Town phase: upgrade production buildings, assign workers around bottlenecks, and research permanent efficiency upgrades.
- Economy phase: add gold production, taxation laws, and trade only when core resource supply can spare inputs.
- Security phase: train soldiers and improve defenses once enemies and combat achievements enter the run.
- Kingdom phase: combine advanced buildings, policies, trade, magic, and achievement cleanup.
Use Official Systems As The Spine
Steam describes the game loop as gathering resources, assigning workers, constructing buildings, researching technologies, passing laws, trading with neighboring kingdoms, recruiting soldiers, and building magical academies. That order gives the walkthrough a safe structure: resource base first, permanent systems second, expansion systems third.
Do Not Rush Every Unlock
A clicker-citybuilder can tempt players into buying anything available. A better route is to ask which upgrade removes the current bottleneck: production, storage, workers, research, defense, gold, or happiness.
