Epochs – Research at Town Center or Capitol

Note: To advance to the next Epoch, you must first complete 2 buildings (except Houses, Granaries, Tower, Walls, Gates and Anti-Aircraft Guns) during the current Epoch. Upgraging a Settlement to a Town Center or a Town Center to a Capitol also counts.

Note: The Epoch advancement costs shown here are the base values used in scenarios. In Random Map games, Epoch advancements are more expensive in Standard games than in Tournament games. Also advancing to the first 2 Epochs from the game’s Starting Epoch is cheaper than usual, that is if the game started in a much earlier Epoch. (For example, if a game started in the Renaissance, advancing to the Imperial Age and the Industrial Age would be cheaper than if the game started in the Dark Age.) The actual costs for each Epoch advancement can be found by multiplying the base value by an appropiate multiplier from the following table:

 Standard GameTournament Game
1st Epoch Advancement Cost:×1.32 base values×0.2 base values
2nd Epoch Advancement Cost:×2.112 base values×0.5 base values
All Other Epoch Advancement Cost:×2.64 base values×1 base values
