Australia is pretty big. I am trying for a samurai-airship feel, but it is difficult. I also forgot that I am isolationist and falling from my seat in the golden age. Falling from gold to ruin is not really my play-style, although ruin to gold can work. Could I maybe do a democratic takeover and shorten my land claims to Southeast Asia and a few parts of Indonesia and Australian coastline? Within that, there will still be an arc, but my people will see it as old vs new, you will see it as honor vs evil unless I miss my mark on Asian culture in that period.
