I found it quite useful understanding all of the terms in civ 6. I'm still in shock the learning curve of the districts, religion, AI is dirt stupid let's face it we all know it. lol
The rest of the game I have fun building up, trying to rush for a victory condition besides War. New terms and game play makes this essential understanding the entire game to eventually master it once the bugs are ironed out or Modders repair them. haha
Enjoy!
