From 2K:
Soon players will have the option to play as one civilization throughout the game, and explore the new Triumphs and reworked Victories systems.
Key changes introduced in the Test of Time Update include:
- Time-Tested Civs - Start a game with any civ from any Age. During the Age transition process, players can select a new civ, or continue playing as the same civilization into the next Age. AI opponents will follow the player's lead, either remaining as a single civ or switching to a new one in corresponding fashion.
- A New Victories System - Achieving Victories have been completely reworked. This new design puts Victories front and center from the start, requiring players to establish clear, undeniable dominance in one of four categories: Military, Economy, Culture, or Science. Players can make progress toward any victory starting in the Antiquity Age, and even win as early as the Exploration Age.
- Triumphs - The team has listened to feedback and have completely removed Legacy Paths, replacing them with an entirely new system called Triumphs. Triumphs offer a wide range of optional, challenging objectives to help each game feel unique. Triumphs are tied to each of the six Attributes: Militaristic, Cultural, Scientific, Economic, Diplomatic, and Expansionist.
