If you are planning on buying this game. I would deffinetly say to you, "Only buy it if you are looking for a fun, layed back kinda game." This is only because of the nature of the game. The game costs alot of money but is a heck of fun to play. You create your ship, You battle other players and you upgrade said ship. This can all be done with a matter of machines, Blocks and tools.
The blocks in the game are standard. Things like stone, wood and dirt. But the way you can use these are much bigger than your conventional sandbox game (I'm lookin' at you Minecraft) You can build your base ontop of a giant pill shaped island. You can mine out Molton Rock to power your Mass Generators (More on that in a bit.) You can use copper to create repeaters to gun down other ships. Iron to make cannons to take out larger ships. This list goes on and this is only the start.
When you get into the machinery such as the Mass Generator or the Energy Storage Unit you get into the advanced Burntout Cores. These cores can be gotten either by buying them from the Merchant Cat (More on him later) or taken from the machine planet. The machine planet is a giant planet made of indistructium, an indistrucatble alloy, with different floors and holes in the side for entering. Burntout cores are the basis for all major machinery such as the Mass Generator which makes your ship create more energy per second which can help you with more thrusters and thus more speed.
The tools aren't very unique with a mix of Guns of Icarus and Minecraft. You have a mallet for breaking things. Then you have tools such as a hammer, a wrench and a fire extinguisher for fixing items. Then you have an electric prod as a melee weapon. Then you have to build a shotgun as a major line of defense. I still find these items unique in a way because they bring their own style to the game.
Finally, everything else. The islands are unique having their own ways of showing. Such as a molten rock planet that you can gain your items for your mass generator. A giant pill shaped island that can be used too create a large base. Normal islands that contain trees on the top and sand on the bottom. The list is endless. But there is one thing in the middle of all of this that everyone loves and often dispise. The Merchant Cat. This cat flys around the different sectors of the world selling goods of all kinds. He is the bane of everyones existance because he gives a warning of getting off his ship within on eminute and can take you off with him to the next sector. But everyone loves him because... Ya know... He's a freeking cat. He sells all kinds of goods. You just need to catch him on a good time. He even buys goods for copper coins so you can buy his goods.
Overall this game is brilliant but if you are looking for a serious game and not a fun layed back one stay away from this. I don't want you soiling it... Goodday players and have a good one.
