Port Royale 1 was the same, but better
1st, you battle with only ONE ship of your fleet at a time, so, if you gather 4 or 5 ships to fight, it wouldn't be as much easier as in port royale 1, where you had them all firing at the same time to ease the job. For instance, if you have 5 sloops, with 60 guys each, you can defeat a caravel with 160 men, just fire grapes with all of them until there is no men in the caravel to repel your boarding. In Sheet Royale 2, you will just lose every ship with no success.
The captains dueling is a good idea, but sucks.
Stay with Port Royale 1, there is nothing this new version has to offer that worths the buying, even donwloading it, just to take a glance.
Hate when they add bad things or changes to what was a real good game, just like stronghold with wronghold 2.
