City of Steam (CoS) was featured in this video by Jiivita.
Omg ruined remains of past oortian culture. (Epic movie voice) A prelude to what exists beyond . . . It knocks on the door, waiting for us to turn the handle.
I think it would be an amazing aspect to add to exos. Even if they were some able to make them special exos. I would go to these to just see the settlements. Even is they were considered museum exos.
And then a titan brusts out of the ground and everyone screams in terror!
Or I like your idea too
Elop-portas (the city of doors) was in the trailer. Both the aquaducts and @H3yjo 's awsom tower and landscape.
I really miss those EA city’s! Therka market and dragons watch were both amazing but nothing toped pixel gate. You could look these up in the search.
Black Light iirc
Also the scene with all the characters waving was the sun / Moon towers made by @SolaTrap. One side / tower was in Elope Portus, the other was on Nashrail somewhere
