Civilization 7's "Time-Tested" civs created a new balance problem, but Firaxis found the ideal solution

The tale of Civilization 7 and its controversial Ages system is now written into history, but it's all about to change with the launch of the Test of Time update. This allows you to carry a single civ through the entire timeline rather than switching out at key junctures. That sounds simple enough, but it presents a whole host of problems due to the underlying balance of the 4X game. In a new blog post, Firaxis Games Design Lead Matt Owens explains how it's solved this by giving its factions ways to adapt to eras outside of their heyday.
