Here's what I'd like to sea
Pets: cats(stay on boat near loot and attack people), monkeys (would sound alarms if boat is near), birds (could be flown to scout), dogs (smell out buried treasure).
New wildlife: crabs, turtles, lobster, rays, whales, dolphin, lizards more fish.
Enemies: more skeleton variety, giant crabs, giant turtles, giant snakes, giant lizards, npc ships, MEGALODON, Moby D**k, indigenous club wielding, spear throwing, bow and arrow using coconut catapult island folk!
Customization: more clothes/guns Changing you ships cannons, wheel, planks, lanterns, anchor etc...
Atlantis and the giant island turtle are a must!!!
A harpoon gun to spear enemy ships to grab onto them with the ability to walk the rope and board their ship, also the Crow's nest needs a rope to swing down from.
Fishing!!!
Different fruits and vegetables each with different healing factors and recipes to craft special items with bonus perks like holding breath longer, extra health, dig faster, run faster, less falling damage, shoot from the cannon further, etc...
There's... More but I say start there lol
