This game is not for everyone. However, for those willing to put in the time, it can be truly addictive and rewarding.
There is an entire community built around this game and I would suggest that anyone playing visit the EGOSOFT web site. The latest manual and lots of player guides on how to start are available. This will take much of the frustration out of it. Also, most people should begin with the Quickstart option.
I agree that starting off blind can be incredibly frustrating. However, after devoting dozens of hours to X3, I've got to admit that it truly can suck you in to the point where many hours of your life can be lost to this game. One things for sure, I'll likely still be playing this game when Terran Conflict comes out.
