Port Royal 3 is an improvement in mechanic for the Port Royal Series, as there are improvements, there are always problem not far behind.
The combat in this version are greatly simplify and easy to handle, but the lack of number of ships in combat, compared to Port Royal 1 is quite disappointing, Port Royal 2 combat system fail to impress me as well due to the lack of ships in combat, but Port Royal 3 did better job then what Port Royal 2 did with its combat option.
The combat system of Port Royal 3 should be maintain but with more ships as Port Royal 1, ground combat for Port Royal 3 is way to simplify as well, but do get frustrating because there's a limit of combat ship to deploy ground troops.
Trading is also simplify and become easily manageable I do prefer this but, it causes the game to be to much of hand holding because of this.
In simple term do I recommend this game? Yes for first timer, hardcore fans might be disappointed but that take it however you like, it's an average game overall.
