I think a new addition to the fleet actions would be a good idea.
So you could go on a Whaling adventure, which would be a two step process. First, you send your fleet on a whaling adventure around a port (like a shipwreck hunt). This phase would take a 6 hour base rate which could be sped up by 20 turns. Once this is done, you will spot a certain sea creature depending on crew and cargo space. Now comes the second phase.
In the second phase, you can choose to send a fleet to go hunt the creature. The creature will leave after 5 hours of you don’t send a fleet after it. You will get food from this so there will be a box to check if you want to either sell food to market or store in warehouse. The time this takes is dependent on a couple different things. The base rate for any creature is | (120(minutes) * 1-10|depending on level. 1 is level 1 2 is level 2 and so on. So at the very max, 20 hours is the longest time this will take. This time is decreased by 1 minute for each cannon in the fleet. This can be sped up like hideout buildings, with each turn invested advancing the timer by 10 minutes. When the hunt finishes, you will get a reward based on
Now for the fun part
All of the different sea creatures you can encounter and the rewards they give.
[NOTE] rewards are calculated by GC= (base value) * 2.1-3 (based on level like the time rate) FOOD: set rate for each creature not dependent on level.
Bull shark- 50k gc 800 food
Hammerhead shark - 65k gc 800 food
Great white shark - 80k gc 900 food
Whale shark - 85k gc- 1200 food
Killer whale - 100k gc 1000 food
Humpback whale - 150k gc 1200 food
Right whale - 150k gc 1500 food
Sperm whale - 200k gc - 1700 food
White whale - 300k gc - 2100 food
The Kraken - 100k gc - 6000 food
The Megalodon - 500k gc - 3000 food
This is just an idea I came up with while showering so I don’t know if this would work. Feel free to reply with suggestions to make it better or to change some rates or equations. I hope everyone likes this because back in the age of piracy there were lots of whalers so I think it would make sense.
