Hey, that's funny....2 other X3-players showing up in the same topic.
And I thought nobody overhere knew about that game!
I loved it!
But I waited with buying X3 right after release, because that forum was simply overwhelmed with game-issues, untill EgoSoft finally managed to patch it to a stable degree...that's when I bought it.
And I played it...nothing else for weeks and weeks.

No wonder, as it took me around 3 weeks to get passed the - insane - learning-curve.
People say that SH3 has a steep learning-curve (?). Well, that's nothing compared to X3, LOL!
But there's this X3 user-interface...
Of course, after a while, I got a little bored, playing only 1 game.
So X3 was shelved, with the plan to return to it some day.
I never did. The userinterface kept me from doing so, I honestly think so.
It's such an incredibly bad design, and in the end it takes away much of the fun.
Take Oblivion, for example...a game maybe just as complex as X3, but with a userinterface that's intuitive and logical.
So X3 was shelved, and along came Oblivion.
And RedOrchestra-OstFront '41-'45.
And then I returned to SH3 - first using the IUB-mod - while waiting for the GWX-mod.
And now playing GWX.
GWX put Oblivion on the shelve again, lol.
But returning to X3? I know there have been some interesting addons released (Bala-Gy's research missions, stuff like that)...but I expect my return to the X-Universe will be for X4.
