The Wonders
Wonders are helpful to you Pantheon for many reasons, the first is that just to have one you receive 5 Resources a turn (some provide extra). A Wonder costs 100 to build and it MUST be paid for at 10 production a turn. However, you don't have to pay for it every turn, you can pay 10 one turn on turn 3 and pay for another 10 on turn 7 or 8 or 9 or 27. There can only be 1 Wonder per Territory. A Wonder will appear in a Territory as a big W, simple click on it and the Wonder will show itself. Each Wonder provides a great advantage to your Pantheon, click on each one to see what it is they do.
