What era is that? We have ships designed in the late 1700s and early 1800s. The USS Constitution caused the British to design a super frigate and completely redesign their 3rd rates. The Constitution was launched in 1797. That means the game should be set in the Napoleonic/War 1812 period in my opinion.
You know, when the irrelevant US navy took on the British navy. Why keep designing games based in the 1600s and 1700s in the Caribbean? That theme and eras are over done immensely.
And again, the largest society is currently a US society, so the US should probably be in the game. Otherwise, we might as well take out the Lynx, Constitution, and Trincomalee for that matter. The first Leda class frigate was launched in 1805...
