In 1815, the Congress of Vienna was held between France, Britain, Prussia, Austria and Russia. The purpose of it was to begin a balance of power in Europe, which ended up lasting until 1914. You can play as any nation in this time period and see how you can grow and expand through military action, diplomacy and internal reforms. Every rwal life day is a in-character year.
The year is 1815. Pick your nation and do what you want. You also get to make a fictional leader or use the real one from that time
I pick Prussia. My fake leader is John Richburg, a 40-year old man who wants to expand Prussia to rival Austria. He wants to be aggressive in his approach but also form alliances and keep France and Russia out of German affairs while weakening Austria.
