Pirates of the Revolution (RV) came out in 2005 as well, featuring the introduction of the American faction. Revolution is sometimes considered the “best” set, with fast ships and some of the most usable ships in the game. RV also marked the first time Events were used, as well as new tins with varying artwork. One of the most historical sets, it’s also a favorite of American fans.
