Okay, the update for Cultural Diversity is ready, but I want to wait - a day - for Hungary to be ready; given the congruency of updating Hungary at this time. So, in the mean time, the details on the Eastern group:
The UI is still a work in progress, but at least it works better this time. With each update I'll change it up until I have the final product. Down the line I will allow you to view the cultural groups of civs in-game, as well as their bonuses, penalties and objectives if you have an embassy with them.
I've decided to take events to heart. These are not random events; they are merely immersive events that alert you to the completion of a special objective (both by you and the AI) and will hopefully enrich the world. There will be two such objectives for each civ group. Credit goes to Sukritact for making the fantastic icon, and to Leugi for the idea of using these icons as a way to represent each group, and thanks to Janboruta for making the Eastern crown. It certainly looks nicer this way than before:
There are also significant updates to come to the Steppes, including a few new Objectives and a variety of different benefits, as opposed to the current culture only reward.
The next group that I will work on will certainly be the Tribal Americans. There was a lot of structural, behind-the-scenes changes that caused the Eastern group to take so long, in addition to the rush to finish the World According to Modders thing (plus a peak in Uni work), but none of these apply for the next two weeks, so the Tribal Americans should not take anywhere near as long.
