I always thought that this image was rapresenting a artwork for Age of Empires 4 but this article shows that it had could be related to Age of Empires Reboot that we didn’t see.
If you are interested
I was imaging a reboot like this but set in the ancient times with a big city and fortress and Great armies. Unfortunately they made Aoe4.
When I saw this image for the first time it made me think that I could build bridges (if you look closely there is a bridge under construction), and that I could make imposing castles as I thought of.
I also thought that this would be the artistic style in which they would be inspired.
Yes, the same. I was very excited when i seen that image for the First Time (one month before the Fans preview on April 2021) because i tought Aoe4 would had have a realistic artstyle, more mature due the Relic experience. I never been so wrong 
The graphic of the game should be better and more realistic.
Building bridges would be very cool.
Hopefully the developers will once improve / develop those things.
