Finish an Era with at least 3 Completed Great Projects
This Development rests largely in your hands. The nature of Projects is that they remain unpredictable, as do their specializations and requirements.
One suggestion we can offer, though, is that you can totally destroy a Project using the Rock Giant’s earthquake if you’re unhappy with what the game lumbers you with. Should a particularly obscure project rear its head then you are absolutely within your power to smush it and wait for the next one to appear. Just watch out, you can destroy resources this way.
The second thing we can suggest is that you create a diverse range of villages quickly if only to grab a spread of ambassadors to unlock all of your Giant’s hidden aspect powers. These are the key to helping you create the right resources at the right time. Unlock these powers first.
And finally? Well, read the Project specializations. Yep, we’re a broken record, but those additional resources are absolutely vital in terms of maximizing your push towards fulfilling the projects.
Just remember, you have to finish with three Great Projects in the world - try and keep in-fighting and sacrifices to a minimum. And if you’re still struggling with this development then finish other developments first, the extra resources you unlock might be exactly what you need to conquer this one.
