Wind is the biggest difference between ST and AoP. Wind is more troublesome than the red zones in ST since there is no way you can beat upwind without wasting time and rations. Also you need "Shot and Powder" or your guns will not shoot.
Also. If you want to be a bad boy in ST there are always the Independent systems you can go to for shipyard and supplies. No such thing in AoP! If you are bad enough, the only thing any port will allow you to enter is the Tavern. In higher difficulties, piracy in AoP is a very costly exercise that should be exercised with extreme care.
