Who said it is 1749? Isn't that /after/ the golden age of piracy? And one could say that Ireland should be in a state of contention with both a national leader and the British king fighting over rule - look up Irish revolutions in the 17th/18th century, I'm sure there's at least one
Also, what would the rules of engagement be? Couldn't some guy kill one british soldier and say he just took over Britain because the king wasn't online to oppose his attack...
Also, we should probably have combat accuracy then
Like... no jumping. People didn't jump over each other swinging swords, they lined up and shot each other lol
