Civ 6 DLC guide

The Civilization series has never reached Paradox-levels of DLC's, but there's now enough Civ 6 DLC, that you may need a bit of help evaluating all of the variety and options. We're now at half a dozen scenario packs, two major expansions and the New Frontier Pass is currently running with six smaller DLCs releasing between May 2020 and May 2021.
Time will ultimately tell if we get anything beyond that or even another 'big' expansion, but in the meantime here's everything you need to know about Civ 6's current DLC library, including all of the smaller DLC that add many new civs and standalone scenarios. This is similar to what happened with the Civ 5 DLC run back when that was still a thing.
We've broken everything down for you below, but it's worth noting that at the time of writing, most of the initial civilisation/scenario packs that were released prior to the Rise and Fall aren't actually available to purchase separately any more. You can typically pick them up together by buying either the Civilization & Scenario Pack bundle or the Platinum edition. The 'New Frontier' pass packs though are being sold individually.
