Played my first game as England, got my PU with France, owned Burgandy, made a fleet 5x larger than any other nation's fleet, but could not defeat Castille and Portugal's navy. It should be easy enough, if I ever caught them! The did laps around Great Britain over and over. I even split up my ships and had them go around both directions, in which case they would go to open sea and around. It was ridiculous! I spent like 5 years chasing ships and never catching them!
