Like I've said before... I'd like to see some land privateer raids. (perhaps in capture the flag form?) You go to their island, capture their "flag" (a gold chest as a piratey replacement for a flag?) and sail it back to your home island. This, in effect, would raise your bounty/score, as well as everyone who was on the ship who sailed it home's bounty/score. The cannons would come in somewhere along the lines of shooting at the large mobs of enemy privateers approaching your fort? Idk, just senseless rambling.
