Looks a lot like and older Civilization and Sim City had a baby.

Roman + Steampunk is not a combination I'd have ever thought would happen but here we are. Color me intrigued. I'll def have to try out the play test. Thanks for the post!

An alt-history world where the Romans discover steam tech and expand into the new world sounds very compelling.

I will add that as per the lore of the game, the Romans discovered steam power and started to colonize the new world. Rather unique I must say.
