Finished the game, but now that I look at all the things possible you can do, this game to me has done a horrible job explaining all this extra stuff and how to get it like the artisans, crafting, armor for your ship. I had no clue about this stuff till later in the game, and by the time I saw that you had to talk to Achilles to get the artisan stuff, it was already too late.
Reminds me a lot of how RE6 was the same way and had you guessing the system mechanics. I feel like I lost out on so much content due to being overwhelmed with mechanics and nothing explaining to use it.
I still don't know about tax rate, or even what lower risk% does after beating navy battles or if you can get more assassins. And I beat the game too. It's so bad at explaining things and I feel I lost out due to it.
