@outragedboss Personally I just hope it's not loot/gold. I want the kraken to feel like an autonomous threat with a mind of its own, where you are fighting to survive, more than fighting just to grind for gold and reputation. But yea, some unique furniture for your ship/decorations, perhaps you can obtain an item 'kraken ink' and after obtaining enough you can buy unique kraken ink sails, etc etc.. that could definitely do some cool stuff like that. A trophy for you ship, for 1 victory, 10, 100 or something.
They also need to make the fight a bit more interesting. I saw a ship get attacked by the kraken, and it was actually better than I thought at the start! Kraken was rocking the ship violently back and forth and all the tentacles moving around... and then the tentacles just stayed in the air and did almost nothing, what? Who on earth programmed that? They need to be writhing about, scary, and the kraken needs to be a threat! Even when they add more AI bosses, which perhaps offer gold or whatever rewards, the kraken needs to be the most infamous and scariest boss in the ocean, with a mind of its own, capable of engaging people any time!!
