20 ideas, let me know what you think. Google Translate abused ;D

IDEAS SEA OF THIEVES
1: Ship Costumization
1: FLAG AND SAILS WITH IMPORTANT CUSTOM BANNER
2: limited and balanced ship upgrade with a slot where you can choose the upgrade (reinforced hull, second row of guns, harpoon)
3 boat decoration and captain's cabin customization
character customization:
1: HAIR COLOR, TATTOOS
2: UNLOCK 1 PASSIVE SKILL AND 1 UNIQUE SKILL ACTIVATED based on the "role of the player on the boat"
the helmsman:
passive skill: speed and maneuver of the boat 5% faster
active skill: when activated for 10 seconds the boat takes advantage of the winds regardless of the position of the sails
the hub:
passive skill: hoisting sails, repairing boats and raising the anchor will be 5% faster
active skill: when activated for the next 10 seconds you will perform these actions 50% faster
the gunner:
passive skill: it can carry 20 cannon balls instead of 10 and loads the cannon 2% faster
active skill: for 10 seconds the charging times of the cannon are canceled and in those 10 seconds 1 cannon will shoot 2 cannon balls together
!!!!!! idea to evaluate
SKILL UNIQUE PASSIVE OF THE LEGENDARY CAPTAIN THAT HAS EFFECT ON ALL THE CREW OR ON THE SHIP.
UNIQUE SKILL 1: CREW HAS 5% MORE HEALTH AND DEAL 5% MORE DAMAGE
UNIQUE SKILL 2: THE SHIP IS 5% MORE RESISTANT AND 5% FASTER.
THE UNIQUE PASSIVE SKILLS ARE NOT CUMULATIVE IN CASE THERE IS A CREW WITH 4 LEGENDARY CAPITANS, BUT AT THE START OF THE ADVENTURE WILL BE SELECTED ONLY ONE OF THESE IN THE CAPTAIN'S CABIN AND CAN NOT BE MODIFIED WITH A COUNTDOWN OF AT LEAST 60 MINUTES.
GAME COSTUMIZATION
1 map spread (already provided)
2 insertion 1 fortress in the center map with 4 smaller forts at the 4 corners
3 merchant ships led by npc carrying goods from the 4 forts to the central fortress
4 chance to conquer the fortresses at the corners having continuous cash advances (low earnings)
5 as soon as all 4 fort corners are conquered, the central fortress will also be conquered, which will guarantee important gains.
6 the central fortress commanded by a player will be attackable always but in time (the time will start as soon as you enter the range of action of the fortress guns), players will have 60 minutes to attack the fortress and conquer it, at the end of these the fortress will be invulnerable for another 120 minutes, IF THE SHIP SINKS DURING THE ATTACK TO THE FORTRESS AND DIES THE FORTRESS WILL NOT BE MORE ATTACKABLE, AFTER 24H THE FORTRESS AND FORTINI WILL AUTOMATICALLY RETURN TO THE NPCS
7 possibilities to create large crews of 16 players with the possibility to have small fleets with up to 3 galleons of 4 players
8 add leaderboard with the names of the ships that have got stronger and are more fearful
9 when you enter the game will be listed on the screen the names of the most important ships currently in the game
10 sinking the most "IMPORTANT" ships will GUARANTEE EARNING AND FAMOUS
11 adding the " popularity" that will be calculated in relationship about pve & pvp actions
12 INSERTION OF CASUAL BOSS WORLD TYPE THE KRAKEN, MAY BE EXEMPLE THE SHIP OF THE DAMNED WHERE YOU GO WHEN YOU DIE (I HAVE ALREADY SOMETHING LIKE)
13 Changing spaw system, we your ship sink you will restart from outpost of another lobby
14 SHIPS ARE CONQUISTABLE, THE ENEMIES SHIP WILL BE CONQUESTED TEMPORARILY, THE CONDITIONS ARE THAT NO PLAYERS OF THE SHIP TO CONQUER A BOARD, TO CONQUER IT NEED TO STAY IN THE CAPTAIN'S CAB, THE SPEED OF CONQUEST WILL VARY IN ACCORDANCE WITH THE NUMBER OF PLAYERS IN THE CAPTAIN'S CABIN. (IF WHEN YOU CONQUER A SHIP, YOUR SHIP REMAINS WITHOUT PLAYER ON IT YOU WILL LOSE THE POSSESSION AND BEFORE IT CAN BE RE-USED YOU WILL RECONQUIST IT. YOU CAN NOT HAVE 2 SHIPS TOGETHER FOR MORE THAN 1 MINUTE, THE CONQUEST OF THE SHIP IS NEEDED TO OBTAIN POPULARITY AND TO TAKE THE STUFF IN ALL TRANQUILITY (AFTER BEING SUCCESSED TO KILL ALL OPPONENT CIOR) AFTER 1 MINUTE THE LAST CONQUERED SHIP WILL SINKS AUTOMATICALLY.
IF WE CONQUER A SHIP BUT THE MEMBERS OF THE OPTIONAL SHIP ARE ON AN ISLAND (MISSION) THEY WILL RECEIVE A MESSAGE WHERE THEY WILL BE WARNED, AND WILL HAVE THE OPTION TO CHOOSE IF FIGHT OR ARRENDING AUTOMATICALLY IN THE NEMIC SHIP CELL, THIS GUARANTEE TO THE WINNING CIURMA A GAIN IN% ON THE GOLD OF THE PLAYER CAPTURED, WITHOUT TAKING FROM THEM
15: The Death: when you are dead in the damned ship you will be responsable of how much time you will need to comeback in the sea world, the damned captain will give order to do on the ship, like ancor seal ecc. when you have done all order you will be able to come back
16 IDEA: ONCE AGAIN, WHEN YOU RETURN TO THE GAME YOU DO NOT RETURN ON THE SHIP BUT ON A lifeboat DRIVEN BY A DAMNED SKELETON THAT BRINGS YOU UNDER THE SHIP (YOU WILL NOT BE ATTACHED UNTIL YOU WILL BE ON lifeboat
17 POSSIBILITIES at every outpost TO PAY TO FILL THE BOATS OF THE SHIP WITH THE STARTING STANDARDS, WILL BE POSSIBLE ONLY IF ALL THE SHIPS WILL BE EMPTY
18 MAKING THE tree OF THE SHIPS DESCRIBED AND REPAIRABLE TO EVERY DATE OR WITH MATERIAL USED TO ADJUST THE BOAT (WOODEN AXES) AND REQUEST FROM 2 TO 3 ACCORDING TO DAMAGE
19 add cannon balls joined by chains
