I mainly picked up this game simply because Re-Logic, the makers of Terraria, said they were behind that game. Now come the 1.0 release, I'm able to give my honest opinion after a couple hours in with a lv. 13 captain:
The game is very relaxing. It's got some humor in it and a couple of references in it as well (The ones I noticed are from Pirates of the Carribean), what's worth mentioning here however is that there is an emphasis on pirates taking dumps, more than you might expect at a glance, which to some is funny, others maybe not so much. That said, you might want to spend some of your first gold pieces on a Cleaner skill book.
Another thing to take note of is that the game still does not have much in the way of content: So far I've only seen pirate ships (Without cannons, we'll see how that works out once I get there) and islands. There is little variety in the types of encounters you might see while playing, which does make the gameplay a bit repetitive. Of course, every one of these encounters will be different, with different ship layouts and assortment of enemies, which makes it feel less of a chore. Also there'll be future content patches for this game, which may further add to the experience.
The game also has a fair amount of equipment for customizing your troops, as well as different combat mechanics such as critical hits, bleeding and of course, the drowning of your deckhands should you get swarmed by enemies that attack one character and there is no wall behind you. This causes slight issues because as I was playing through this game I did not manage to have complete control over what enemy my deckmates were attacking, which makes the tactical element of the game a bit harder to execute.
There's plenty of charm in the game as well. Many of your new recruits have "special" abilities that makes them interesting. I had one that made my pirate attack its teammates every once in a while, resulting in him eventually getting killed when vikings boarded my ship. There's plenty more out there and that is something I definitely approve of.
That said, it is an indie game, and for it being an indie game it's definitely not bad. I quite liked spending some hours seeing my Dubstarr & Co. slicing up enemies with his Falcon Blade, and come another day when I fancy some pixellated pirate caretaking, I'll probably look back at my save file and play some more.
Plus for what you pay for it, this game's worth it. Especially now with its launch deal of -50%.
