What era you’re moving into will determine how many you want to have. Setting a goal amount before moving up, and achieving that goal is recommended. Most won’t run out of coins because you get plenty with aiding, but supplies are a bit more lucrative. Remember too that you’ll be changing out your buildings, and this also costs coins and supplies. Making sure you have enough going into the next era will greatly help your ease of moving through the era to get what you need without much delay or headache. This often costs goods, supplies, and coins in various combinations. When you age up, you’re going to be researching technology, and therefore unlocking it. One of the biggest things is how your stores look. So where is that delicate balance? It will vary for each individual play style, but these are some general things to consider. Moving up too fast means you can’t strengthen your city to be able to handle it, but moving too slow means you’re hindering your growth and potential. One of the trickiest balancing acts of the game is definitely deciding when to move up, and when to stay put. You get to grow and explore further, but at the same time you’re going to be fresh and vulnerable.

Aging up and moving into a new era is both exciting and terrifying.
