Finish an Era with at least 1000 Wealth being used by Villages
The focus with wealth are desert villages using the Rock Giant’s minerals and the Swamp Giant’s animals. The aim is to cover the world in such goodies to attract a lot of villages and supply each with a chunk of the wealth.
Start with Quartz by Quartz, primarily. This symbiosis will generate a lot of wealth quickly. Over time, however, it’s recommended to upgrade Quartz to Onyx, and then add plants next to these. This is particularly worth doing after earning the ambassadors required to unlock level 2 minerals for the Rock Giant.
War can be an issue in ths development so rather than focus on one village at a time spread minerals worldwide and sparingly at first. You’re trying to keep a village’s potential resources close to their actual resources to keep greed down, so make sure resource addition to each is ticking over at a slow burn instead of focusing on one town, then the next, then the next etc.
