This scenario, designed by Lupo, is different from the Genua available in the downloads section. I got this from an Italian C3 site, which seems to have shut down already. The map can still be downloaded via web archive.
As to the city layout, I added a mini-goal of building a remote palace on high ground which was on the far corner of the map. It's also a nice bit of challenge trying to integrate it with the rest of the city.
Played this on VH using Julius 1.60, with no debt, no gifts, no blessings, with upgraded buildings.
I'm listing a couple of maps here suitable for this remote palace mini-challenge (with the aim of still finishing the other scenario requirements). One is Calgary by Caius Menginus, with the palace location on the northwest corner plateau. Another is Leptis Magna by Barberousse, with the palace on the southwest corner plateau (either beside the native trade hut or outside of it).
