"Some great news for anyone that owns a copy of LGP's X3: We've been in contact with Egosoft and they are working on adding all your LGP keys into Steam. Which means you'll benefit from future updates done by Egosoft themselves as well as have access to your game from within Steam in the near future."

That's handy then seen as there version don't like AMD cards on the cat drivers.
Wasn't expecting them to do that in all honesty.
Just put my code in and its worked, side note! don't include the - in the serial.
It did throw an error to start with but is downloading though.
Pete.
It worked this time, yay!
Most obvious changes from LGP version (so far): config program was re-written for GTK2 and is now a separate binary, graphical artifacts are gone, ships with recent library builds, links to SDL2, and currently has worse joystick support (can't get the POV Hat to work at all).
And best of all: it doesn't link to steam and runs without it!
