In terms of setting the bar for Features and Editorials, Polygon has steadily maintained that title with relative ease in comparison to its more breaking-news oriented competitors. With topics ranging from an Oral History of Street Fighter to a Photo Essay of Gaming in West Africa, Polygon has continuously stretched boundaries of what and why Gaming journalism is.
This particular post, published yesterday, is a great example of Polygon doing their thing. I never realized that the landfill excavation took so long to get off the ground, and reading about how this important (for Gaming Historians, at least) dig became tied up in local politics was also interesting to discover. If the news stories about the Alamogordo dig refused to satiate your urges for more information, let this article by Matt Leone satisfy you.
