Mr. curious is referring to the fact that the CE was supposed to have "exclusive" preorder DLC. Then CD Project had massive issues with their shitty launcher when TW2 came out and instead of fixing shit, they decided to just go feck it and gave away all of the DLC for free to everyone including the CE preorder DLC.
Like Mr. curious I also fell for their little preorder scheme but again like Mr. curious I have also learned my lesson.
At least with CDP games I will never again preorder but just wait and see until they release the inevitable Enhanced Edition a year after the main game. Saves ya lots of money and headaches and you get to play the full game like it was meant to be on release, too. Win/win.
