There is a simple version of this and a complete version, and both are below in that order.

Short answer

Do the simple thing first. It is correct more often than the complicated thing people recommend instead.

  • Do not build a routine around an edge case.
  • Test it yourself where testing is cheap.
  • Expect one number in every guide to be out of date; the method is what matters.

Each Civilization entry reshuffles the rules enough that habits from the last one quietly stop working. Edge cases are genuinely rare, which is why the simple answer is usually the correct one. Nothing here depends on a setting you are unlikely to have.

Why it works this way

Half the pages on this topic were written for a build that no longer exists, which is why they stop matching what you see. Testing this yourself takes a few minutes and settles it definitively. The accepted community answer is broadly right and wrong in a specific way that matters here. If your result differs from what is described here, note what is different first rather than starting over.

The mechanic behind it is simpler than the discussion around it suggests. Most of the disagreement online comes from people describing different versions of Civilization. There is no hidden trick here that the game is keeping from you.

Worth knowing alongside this

It is worth separating what the game does from what players have concluded it does. What follows assumes you are on a current install and have not modified it. There is usually a fast way and a reliable way, and it is worth knowing which one you are choosing.

  • Check which version any conflicting advice was written for.
  • Revisit after a major patch if the behaviour changes.
  • Prefer the in-game option over an external tool when both exist.
  • Note the exception cases — they are specific rather than vague.

The practical answer

None of this needs a paid tool, a third-party launcher or an account on a site you have never heard of. Screenshots age faster than text, which is why this describes rather than shows. The awkward part is rarely the step itself, it is knowing which step comes first. It helps to understand why a step exists, because then you can adapt it when your situation is slightly different.

Nothing here assumes a particular playstyle beyond wanting the thing to work. Do the cheap check before the expensive one — that ordering alone saves most of the frustration. Most of the disagreement you will find online is two people describing different builds.

What to do instead

A single check up front replaces a lot of guessing later. Everything below is framed around the current state of Civilization rather than a launch-week impression. Civilization is not shy about hiding useful information two menus deep, so some of this is simply knowing where to look.

Anything that behaves differently on console than on PC is flagged where it matters. The community wisdom on this is roughly half right, and the half that is wrong costs the most time. If a step reads as obvious, do it anyway — the obvious ones are the ones people skip and then wonder about.

When the usual advice fails

Patch notes move numbers around constantly; the shape of the answer holds even when a specific value shifts. The short version is near the top on purpose; the reasoning is there if you want to know why. Treat anything stated without a version number as provisional.

Where people go wrong

  • Treating a rare edge case as the normal behaviour and planning around it.
  • Rushing the last step, which is usually the one with the actual requirement in it.
  • Copying a setup wholesale from a streamer without understanding what each part does.
  • Grinding a method that was patched months ago because a thread still ranks well.

Civ FAQ

Does this change between platforms?

The behaviour does not. Where menu paths or prompts differ, that is noted above.

Do I need any mods or third-party tools for this?

No. Everything described here works with the base game on any supported platform.

Is this still accurate after the latest Civilization update?

The method is; individual numbers may not be. If a value on your screen differs, trust the screen and keep the sequence.

How long does this take?

Minutes if it goes cleanly, an evening if you hit the edge case in the caveats list. Neither is unusual.

Come back to the caveats list if it does not work first time — the answer is almost always in there.
