1. THE DEMOGRAPHICS.
They were astonishing in Civ4 BTS. And don't tell me those stats told too much of the other civs, they know all of human player anyways!
Just loved to take that peak every 20 turns or so, where are we on economics, military, etc etc. At least these should be there when spies are in another civs!!
When the game is over, you lack the possibility of comparing stats per 50turns, per 100turns etc. Also, there should be the graphs per YEARS AD, NOT by turns which is useless!
This is my single most frustrating thing. As well as the one that should be informed to the civ6 developers!
What's yours?
