Do NOT buy this game. It is plain and simply a mismanaged jumble of development for a product people didn't really want.
What people wanted: a pirate game like black flag but with MORE
What ubisoft made: a game where you play as a pirate ship with LESS.
16 hrs of play and i have literally beaten the story, gotten to max rank and made the largest ship. Once you do this it is just senseless grinding to get marginally better weapons and the progress is VERY SLOW and VERY BORING.
This game is took features from Ghost recon (with the ports you can "walk on" basically functioning like the hub from breakpoint)
They took a loot gear system similar to the division but with 1000% less variety and made it grindier.
There are a couple of ways you can equip a ship but ultimately there are only a few classes (roles) and they kinda define how you SHOULD build your ship which just leads to basically always using the same stuff.
Barely anyone plays the PVP modes, people do join the PVE stuff but honestly its not really any more fun doing either of those two things anyway, the PVP stuff is just take a port whilst versing players and the majority of PVE is just kill a ship that has its health bar turned up to the sky (like versing bosses from division 2 on the higher difficulties)
I remember hearing about this game when it was first announced and showcased, and it was intriguing but seemed like a shell of what black flag was (which is what this was originally meant to follow up on as a stand alone black flag experience). After all this time its sad to see it never came out to be what the players wanted and after being a part of the alpha and beta tests its even sadder to see that just none of the feedback was taken on board (pun not intended) and the game was released anyway.
