I was thinking about buying the Wonders and Artifact DLC. So far I've only found list that tell what they are, not what they do. So I was wanting to know what these things do before I actually buy the DLC cause if they don't do anything great then I won't buy it. Because it's not worth wasting money if they don't do anything that great anyways. So a list of wonders and artifacts and what they do would be great. thanks.
