I have. It's not very good.
The game has no land combat, just wandering around in hubs to collect missions and stuff. The character creator is a fucking joke. The ship combat is worse than Black Flag because you can only have one unique type of cannon on your ship at a time. One. So green, blue, purple rarity stuff right? You can't have more than one from what I can tell. There are more ships and they fit into the DPS, Tank and Healer category for some God awful reason.
I just want to say that back in 2008 there was an MMO called Pirates of the Burning Sea. It had a better character creator, it had swashbuckling and land combat, it had FUCKING BIG ASS WARSHIPS. You may have traveled on a map, but by fucking God it was somehow less monotonous than having a FUCKING STAMINA BAR TO GO FULL SPEED AHEAD. The sea combat is arguably better than Pirates of the Burning Sea, but you can't board the other ship like you can in Pirates of the Burning Sea and take it or turn it into a certificate depending no your class. You just hook them and it says you succeed if you succeed, no battles and the ship is destroyed.
OVER 10 YEARS FOR THIS GAME AND A GAME THAT'S 15 YEARS OLD DOES IT BETTER.
