After years of playing on and off again with over 500 hours both on and off Steam under my belt, I can say this is my favorite game. This won't be universal, though, as the game has a very large learning gap and very little instruction, coupled with a format of gameplay that is best discribed as "love it or hate it". The lack of a tutorial doesn't help.
For those wondering if this is worth playing or buying, one must ask themselved what do they want first. Do you want to be a pirate in space firing on ships outside of the areas controlled by the law, and don't mind the high dificulty?
Do you want to spend many hours trading items from one station to another to gain money and eventually buy your own states, hiring ships to trade for you and leading your new found corporate empire to grand wealth?
Do you want to explore the universe, and all it's mystory and see it's dark secrets, with all the risks that may bring?
Do you want to be a cop, shooting down pirates, evil robots, evil incests and whom ever else may oppose order?
This and much more is in the game.
However: if you want instant gratification, always playing at a fast pace, or everything being handed to you?
Then this game is not for you.
