With a renewed interest in research of Firaxis logos hidden among Civ VI leaders, @AriaLyric and myself have found quite a batch of new info in the SDK Assets downloadable from Steam. Among our new discoveries weren't only logos - we have actually uncovered some more complex content that doesn't seem to ever have been shown to us. As the assets appear to come from different stages of development of the game, there's a lot of things pointing to various interesting processes that may have happened during the development of Civ VI. There's a lot of small, unexpected details, like an unused background for Teddy Roosevelt or this weird placeholder of 22 Montezumas : Spoiler : There's also plenty of other things related to the Aztecs, more than you'd expect. Among the most interesting is perhaps the two-headed snake, which the game uses as Aztec's in-game logo, labeled as 'CivPoland'. All this seems to suggest that the leader and civ roster that we know from our final game may have been different at some stage, with Aztecs possibly not being a preorder bonus. 22 was also the number of leaders found on the leaked leader chart (the one that famously didn't include Tamar of Georgia) But there are also some bigger discoveries. The most interesting to me is what may be textures for a completely unused leader. I have posted them earlier in the logo thread, and here they are again. Spoiler : There's a theory I had on the leader in the logo thread: The 'test' in the filename possibly indicates that the texture could be the very first that was made for any Civ VI leader model, and therefore it could be unrelated to our final roster. It may have been made for a potential DLC leader, which would fit my theory from the 2016, when I thought that the colors of duplicate civs that would appear in the game were related to DLC civs. There's a post I've made on the topic. https://www.reddit.com/r/civ/comments/5vq8y2/ive_made_a_little_investigation_into_the_topic_of/ Before the first DLC releases there were four color schemes that would appear consistently: the first two ones exactly matched what would become Poland and Australia's colors (from their First Look videos), the other two didn't end up matching Persia and Macedon, however the purple-orange one almost exactly matches Cyrus' gown: This green texture of our unknown test leader may actually corespond with the last duplicate jersey that appeared in the game back in 2016. The dev assets indicate that there were some shuffles with the roster, and all this evidence may point to the most radical change that occured during the development process. Perhaps it may even explain why the Viking DLC was the only one not to contain an additional civ? remember the wooden leaderheads? could our guy be Charlie the Great? It may all depend on who this guy is. I can't quite put my finger on it, but he really does seem familiar to me. There's probably much more that I have no idea how to access, maybe even a model and animations for the guy that we have found. There was an interesting thread on r/civ around the release of R&F, which showcased an alpha build that somebody seemed to have somehow accidentaly downloaded: https://www.reddit.com/r/civ/comments/7ws623/accidentally_got_an_alpha_build_of_the_expansion/ With the SDK Assets, we have a huge database with potentially dozens of things like this to find. I think it's worth a thread and an investigation.
