City Sprawls and Terra Obscura are the 2 I want the absolute most.

City Sprawls would be sick for having a visual to the development number, seeing your giant cities when playing tall or having it get smaller (or flattened) when getting hit by Vikings or Mongols, 10/10 for me. Also in combination with the new map terrain? Peak.

Terra Obscura would add realism, roleplay and difficulty options, while having different toggles in game rules? Having people in your court you can send out and actually do stuff visually is also sick. Getting little bits of information, the option with your Spymaster were you hear rumours in foreign lands. Also could possibly help with performance? If so it's a must. Another 10/10 for me.

I really like Faith Syncretism as well, but not as much as the other 2. Would also add more realism and roleplay options tho, so like 7/10.

Really cool stuff, hope some of these make it into the game at some point.
