About the only info we get at the start on this screen is soldiers. Normally I ignore the Demo screen, but since it is for the glorious SGOTM I'll indulge just this once.
Demographic Guide -

Emperor AI Starting Soldiers:
Every emporer level AI starts with 2 archers, 2 scouts, and 1 settler.
To get the archers, the AI also receives hunting and archery along with their 2 starting techs.
From the Demo Guide, the following techs and units are relevant at the start:
2000 Soldiers - Hunting
6000 Soldiers - Archery
2000 Soldiers - Mining
4000 Soldiers - Wheel
2000 Soldiers - Warrior
3000 Soldiers - Archer
4000 Soldiers - Bowman, Skirmisher
If the AI does not start with Mining or The Wheel, they will get 8000 soldiers from hunting + archery, plus 6000 soldiers from two archers. The
lowest rating emperor AI can have is
14000 soldiers.
16000 means they start with mining.
18000 means they start with the wheel.
The two special cases are Hammurabi and Mansa Musa.
Hammurabi gets 8000 soldiers from bowmen, and has the Wheel. He gets 20000 soldiers.
Mansa Musa gets 8000 soldiers from skirmishers, and has both mining and the wheel, the only civ to get both as starting techs. He gets the maximum of 22000 starting soldiers.
Soldiers are independent of team play, and are seperate for each civ as normal on the demo screen. A 3-civ block will not have 60000 soldiers at the start. However, the team play means all techs are shared at the start, so Hammurabi can start with 22000 soldiers if he pairs up with a Civ that has Mining.
From the starting screenshot of our game, we see that Rival Best is 22000, Rival Worst is 13000, and the average is 17875. This means we can draw two conclusions.
1)
Mansa Musa or Hammurabi is in our game.
2)
A civ that starts with mining (16000 soldiers) has had one of its two starting archers taken from it on purpose.
Additional Analysis: 3v2v2v1 or 2v2v2v2?
There is no way of telling.

An average of 17875 soldiers can be reached in the 3v2v2v1 case with 22k,20k,20k,20k,20k,14k,14k,13k. An average of 17875 soldiers can also be reached in the 2v2v2v2 case with 22k,20k,18k,18k,18k,18k,16k,13k.
