Buy ONLY if you have the patience to learn to play an absolutely astonishing game in detail, I did for 178 hours and I would play another 100 if I had time.
I will list all the positive and negative sides that I can think of;
* Open World
Open Space in fact, because it is reaaaaally large
* Very limited Restrictions
Almost none frankly
* Multiple Approaches to gameplay
Be a grand industrialist, Trader, Pirate, Pilot in Military, Monopoly or go mad and be a terrorist in terran space!... or ALL OF THEM
* Constant progress
Thats right, there are plenty of things to do and improve, you won't have so much time to finish all the projects you had in your mind
* Interactive World
Some games offer just open world, here, you can literally affect the way things work... With consequences.
* Virtual Economy
You can affect or be effected by wide and witty created economy system, dont expect a huge touch in this, but know that it will certainly spice up the gameplay
*Variety in Ships/Stations
The spaceships you can use, destroy, board, capture or disable are plently. Different classes (Scout, Fighter, Heavy Fighter, Destroyer, Carrier, Transport, Cruiser, Capital Ship, Boarding Ship, Missile Boat, Lasertower and many more)
Each Race owns different stations with different properties which require different materials, goods and also provide different resources or weaponry parts etc.
* Quests, Tasks, Missions
Besides the main story, there is a VERY large range of things to do in the game.. Buy the asteroid data or sector maps, build stations for others, follow ships to their secret meetings, escort or raid ships etc. You will find many things to keep yourself busy if desired.
* Immersive Design and Fluentness
It may sound weird, but you know there are some games that you want to play awhile but ending up playing hours of it and not even know how the time passed... Yeah, its that because there is always a great transition between the things you did, can do and will do in the game that you wont find a proper time to say : Ok Im done with it for today
* Harsh environment
You can deny if you want but we all know that is always better to succeed a hard task than a simple one... Sometimes, your mistakes or miscalculations in industry will cost you severely. Good thing is, there is always a way to bounce off the bottom rise again, it pushes you to think while playing too.
* Quality Soundtracks
That is actually my opinion, but usually every sector you fly to will put you in the mood of that zone... Except combat, combat music is a bit.. meh... But again, that is just my opinion
* Mod Support
Does this Need explanation? Very large texture or gameplay mods to improve gaming experience... DUH!..
* Insufficient Tutorial
Well the game does have a tutorial system, but just enough to say "yes it does have it" it only teaches you the basics and the most fun parts (advanced systems, complex installations, running economy, ship design and weaponry etc.) are either learned from the internet or experience... It was both in my case. So be patient if you really want to taste the game's true potential and trust me, its not Quantum Physics, you can get the hang of it in no time.
* Needs more User-Friendly Prompts, Commands and Interface
What I mean is, this game is very deep and large in scale and detail that even though game offers very advanced and complex ways to fulfil your tasks or goals you still need various interactive ways to make things more accurate or better. It falls victim to its own depth in gameplay. (There are plenty of mods to improve this, you can still be satisfied with the current system if you aren't a fan of mods and prefer vanilla experience, so no worries)
* Minor AI problems
As I said, they are minor... Sometimes (Rarely) a huge transport ship you hired from Paranid Empire can not fly to the jump gate because of small asteroids or similiar objects and detours indefinitely. This has very simple solutions with no fix or mod requirement (like flying out of sector and waiting for it to come) and similar little problems like these. In case it is needed, mods to fix these issues can be found throughout the web.
* Needs More
Yes, yes I know I said this game has plenty to offer but you would understand if you played. They make the game so large that you will start asking for more even though it has serious amount of features in it already... Frankly, they released a patch (which is in expansion pack size) with a whole bunch of new things and 2 major storylines and more sectors with races and such... The developers provide, respect.
I would give this a clear 8.5 / 10
Mainly because it gave such an experience that I bothered to write a review about it!... Oh yeah, its my first review. Hurray.
Also, I have played EVE Online for 4 years so if you already know that game, you will be familiar with the concept of this game. I also recommend X3 Terran Conflict & Albion Prelude to those who own the latest X title (X Rebirth) because you will witness completely different experience nevertheless!
