Empire Earth - Technologies
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 Game | Tournament 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 |
