Question 1

How are these civilization matchups calculated?

Accepted Answer

Each matchup win rate is measured from real ranked 1v1 Random Map games on patch 162286 — civ A's win rate against civ B across every game the two were drawn against each other.

Question 2

What counts as a good or bad matchup?

Accepted Answer

A win rate above 50% means the picked civ tends to beat that opponent; below 50% means it struggles. The further from 50%, the stronger the edge — but check the game count, since rare matchups have noisier numbers.

Question 3

Are these matchups from the game files?

Accepted Answer

No — the game files contain no balance data. These are empirical results measured from real ranked ladder matches, so they reflect how the civs actually play out head to head.
