I like this game! Its very colourful, its not meant to be a historical recreation of pirating & its addictively fun!
Your character starts off with a ship, a crew & a pirate base to sail from. The game is mostly quest-driven, the goal being to complete quests for the different factions in the game (there are three), which rewards you with gold & reputation with that respective faction. The ultimate goal is to unite the three factions in order to take on the dreaded Black Cove Pirates & then become the Pirate King. Your character gains experience & reputation along the way, which unlock new skills. Your ship can be upgraded to become ever more powerful & you can recruit a pirate army to help you plunder colonies around the Caribbean. I found that the game mechanics were quite intuitive & its not a game you need to spend hours poring over a manual or practicing detailed tutorials just to play.
Sea combat is very easy & basic, but I have found it to be less cumbersome than the mechanics in "Sid Meier's Pirates! Gold". If this game were only about sailing around, fighting other ships & plundering gold from their wreckage, it would be a boring game. But it isn't. Its about questing, accomplishing missions, gaining rewards & experience, & following a storyline. That keeps it interesting & fun & not too serious, enough to hold the player's attention. There are loads of corny pirate jokes to be picked up in bottles floating in the sea so you might even get a laugh out of it. I think the developers have done a lot of work trying to make the game as least serious as possible, to make it a fun game to play rather than a simulation.
At the price that its being offered on Steam, in my opinion it is worth the money. Its becoming one of my most enjoyable games to play :)
