seems like I get era score for a canal when building Panama canal, so perhaps.
That engineering one I'm still working on. The save above has mods, and I would rather not use that. I make a point to post saves without mods. I also still need to do the one with all the renewable power plants in the city. That one is surprisingly difficult to plan as well.
And the Canada emergency achievement I don't know what to do about, I can't get it. The Rome one will be extremely difficult as well. I don't think I've even seen Vesuvius in a game.
edit: And for some reason I can't build dams on the Earth map. There aren't many rivers with flood plains on that map, and the ones that are you can't build dams on, and I'm not sure why.
