My first in the X series. I love the dynamics and can't wait to try some sequels.

So, a quick review of X2 The Threat.
X Games are a genre unique unto themselves. The game is basically a sandbox universe made up of multiple sectors or solar systems connected by jump gates.
The main objects in the sectors are factories which consume and produce products; and different kinds of space ships flying about doing different tasks; such as freighters collecting or delivering products, military ships defending the sector, pirates doing their business (they don’t bother you too much), and a mysterious enemy called the Khaak (that will bother you relentlessly).
You can choose the kind of role you want to play. Be a pirate hunter, stealing their ships and selling them. Become a pirate yourself if you want. Build a commercial empire with factories in multiple sectors and your own fleet of freighters – and get rich so you can buy the high-end ships and equipment and go and conquer the universe. It’s really up to you.
There is a storyline you can follow if you want. It’s not great really; but you can drop in and out of it as you like.
X2 is not an arcade space dog fighting game. If that is what you want you will be disappointed. The game requires a lot of time to learn and play. For those who like sandbox simulation games, with an emphasis on building an empire from scratch X2 The Threat is excellent. Although that said the subsequent iterations have improved the gameplay and graphics. So if you want to play just one X game this might not be the one to choose. The whole series is available here on Steam, so do a little research and decide which one you want to jump into.
(ps I have the game on Steam but I played a retail copy)

If you're into space sims this is a good one. It emmirses you in space and you don't know where to go first.

I've been playing this alot the last few days and its a great space sim, However like others said the learning curve is tough and several times i've been left with no idea where to go or how to complete a mission. Still its fun and well worth the price. Its a timesink, but once you figure things out you'll have a blast with this game!

I love this game. Open ended and the first occurence of the Kha'ak.
