Ancient Wonders is an expansion to Origins: First Builders and consists of two separate modules which can be added to your game separately or together.

Ancient Wonders
This module enables a new type of building that can be added to your city, eight majestic ancient wonders that bring more variability and options to the game.

Trials of the Builders
End-of-round scoring objectives require you to find the right balance between pursuing advancements required by the current round objective versus progressing the personal goals you have set for your civilization already. This module also brings a predetermined length to the game, eliminating all other end game conditions.
