I've got X3: reunion on steam.. bought it late 1 night and gave it a try and didn't have a clue how to play/what I was doing! From the sounds of it, could be worth giving it another shot
is it anything like the old wing commander games? loved them!
X3 is an absolutely amazing game, IF you give it enough time. The learning curve is like running into a cliff at first, but dedicate some time to it and you will see what an immense gaming experience it can be.
You can build yourself a trade empire with factories and bases across the galaxy. Or you can be a lone gun and just run missions and attack enemy sectors.
X3 is not a game where you can do things quickly, if you wish to build factories and what not, be prepared to plan carefully and methodically and it will take time to assemble.
The manual in no way prepares you for the depth of the game, i read it and beyond telling me the controls it was mostly useless.
So, go here and download this guide:

And make sure you patch it up to its latest version.
Also, a joystick will make the whole game about 10x easier to play. But the game is worth it, if you get into it, then prepare for hours/days to disappear.
