Good graphics, boring and pointless game. Even the combat has become easier and I thought that was impossible. They've even managed to add a few hilarious bugs to the combat system that never was there before. The idea (Pirate game) intrigued me though, so I bought it even though I suspected it was poorly done and gimmicky and I suspected right. The waters are too full of ships, floating cargo and wreck survivors and the naval fights are short and not very exciting. There is loot virtually EVERYWHERE on islands, coves, sunken wrecks, in the middle of towns and cities... everywhere. It shouldn't be referred to as "Treasure" when it's the far most common thing in the game world.
You can basically sail 300 meters outside the harbor and boards ships there until you got few crew members and sail back in. Nobody gives a flying fuck that you've just wreaked havoc just outside town. There's also an abundance of pointless gimmicky stuff to do. The crafting system is pointless, because it's pointless. It would be much more logical to just buy the damn armor pieces and ammo pouches since there are shops around.
Your armor doesn't change visually as you upgrade it, it's already visible before you actually get it. The different outfits aren't really that much different except for some those implemented from previous games.
I could go on forever... The game is probably fun if you enjoy pointless achievements and massive & repetitive time sinks. I can't really comment the main story because I found it so scripted and railroaded that I stopped playing soon after getting the base. It's like most of the other iterations except for the original, it's not really bad but it's far from good and once you're finished you wonder why you had to do over 80% of the stuff the game made you do.
From the beginning of the game I picked up all treasure I could find and by the time I had a ship and were allowed to upgrade I upgraded gun damage and have blown everything to smithereens ever since. So if you're going to play the game and have any resemblance of difficulty in it, don't upgrade weapon, handgun or armor and upgrade your ship evenly, a point here and a point there as you progress.
