Echoes of Earth update: Wonders of the New World

The “Wonders of the New World” update has been released!  This large update changes all the Wonders in the game.  Wonders in Echoes of Earth have three core properties:

1. Wonders provide unique local effects
2. Wonders provide one-time Affinity points when built
3. Wonders require Geothermal Resources to build

You can see pictures of all the new Wonders at the official guide.  In this post I want to describe the design problems I wanted to solve and the advantages this approach provided.
