- Ancient Era (previously Bronze Era)
- Classical Era
- Medieval Era
- Early Modern Era
- Industrial Era
- Contemporary Era
- subject to future change before Release, as with almost everything, and adding the 'preliminary' Neolithic
Relating these to 'generally accepted dates' which is the best we can really do because almost no one agrees on all the start and end dates for the artificial 'Eras', might leave something like this for the game:
1. Neolithic Era - 10,000 - 5000 BCE: earliest Agriculture to earliest copper anneaing and working and start of arsenical 'false bronze'
2. Ancient Era - 5000 - 1000 BCE - earliest organized Cities to start of general Iron Working and horseback riding
3. Classical Era - 1000 BCE - 500 CE - start of pastoral horse-archer cultures to end of Roman Empire
4. Medieval Era - 500 CE - 1500 CE - I'd prefer to put the date back to 1400 CE, but that's not the general consensus
5. Early Modern Era - 1500 - 1750 CE - end dates vary from 1700 to 1800, so 1750 is a compromise
6. Industrial Era - 1750 - 1945? CE - end date is really flexible, ranging from 1880 to 1945, but see next:
7. Contemporary Era 1945 - 2020 CE - 1945 is the earliest date I've seen for this, but some systems assume it did not start until 1970 or 1973. That, however, makes the 'Industrial Era' much too long and too full of everything from flintlock muskets and Frigates to jet fighters and Satellites, so I suspect they will use the very start of Atomics and Jets in 1945 as a cut off.
From what they've indicated so far, the 'Neolithic' is Pre-City, in that you cannot even choose a Faction to play as until you reach the end of that 'Era', which makes it a sort of 'Pre-Era' or Extended Starting Turn for
Humankind. It will be interesting to see what elements of game play, like Culture, Technology, or Social Organization are available in this 'Era', if any. It also means that in Game Terms, the end date for Neolithic and Start of Ancient, the first 'real Era' are probably the most flexible of all. If, nominally, it starts when you build your first city (sorta like Civ's traditional 'First Turn') then historically it varies from 6500 BCE (Mesopotamia, Anatolia) or so to as late as roughly 300 BCE (Celtic Gauls), which is a wider range than the total length of any other Era!
