Port Royal 3 is an improvement in mechanic for the port royal series, as the 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 ship combat similar to port royal 1 is quite disappointing, port royal 2 combat system fail to impress me but port royal 3 did better then what port royal 2 did, the combat system of port royal 3 should be maintain but with more ships as port royal 1, ground combat is way to simplify as well, sometimes frustrating.
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.
