they have also started a thread called: Important:Competition: be 1st to build a 2nd city
And this is what they wrote:
We need to show the rest of the world that we're the biggest and the best, and the way to do this is to start building cities. In many ways, the second city can be the toughest, so the competition is on - who will be the first to get their second city?
We will be inaugurating a Second City Club - a thread where we pay tribute to the first members to take their second city. Other members should feel free to shower the winner with gifts of resources.
But we're also an all-for-one, one-for-all alliance. The aim is for everyone to build a second city as soon as possible. If you are struggling to grow, let us know. There are lots of experienced players in this alliance who can give you guidance.
Chances are your second city will be a colonisation, as you can colonise before you can conquer. But once you have a second city, you can then start to Conquer!
