Very nice collection, and nicely organised. That's a lot to collect in just six months.
So do you have a 3-way ongoing battle between Pirates, Spanish and Bluecoats (maybe French)? You could easily add some Redcoats as the English, and split the pirates into two factions, thus making it a 5-way battle with 3 nations and two independent pirate groups forming different alliances and so forth.
Lots of fun to be had from the Pirates theme, and it's still going strong.
