The short version of this is you are stuck in whatever age you are in until you click an "age advance" button that advances you to the next age. When you advance age, a crisis of some kind is triggered that your civilization must overcome.
So for example - Rome tries to age up from the Classical to Medieval era. It experiences an inflation crisis, which causes gold maintenance costs to drastically increase for 5 turns. If the treasury hits zero, units or even entire cities revolt to avoid the treasury going negative.
As another example - Germany tries to age up from the Renaissance to the Industrial era. It experiences a crisis of religion, whereby about half of its cities suddenly convert from Catholicism to Protestantism. The Protestants ask for you to adopt Protestantism as the new state religion and depending on your choice, the other side will spawn rebels or even a new civilization.
I would also like to see sort of a "conflict harshness" - whereby the earlier you try advance the more difficult a crisis you face will be, as an anti snowball measure.
On the science side of things, you just keep researching tech from that specific era. So for example you might research barter (unlock markets) then currency (market yield increased) then coinage (market yield increased again) etc. Each era would need many more technologies than what we have currently (or alternatively it's like Iron Mining 1/2/3 each time revealing more Iron on the map).
