I got my Game in the Box Limited Edition the Handbook did not have the Key, I did not panick, I went check my Email it was there!
Dear customer,
Congratulations ! You are now among the first owners of Cities XL, and we hope you will enjoy the game as much as we enjoyed creating it.
You will soon be able to create your modern empire and become a successful mayor.
Before you do so, you will need this CD Key to complete the game's installation once you have received the box:
XXXX-XXXX-XXXX-XXXX-XXXX-XXXX - not showing the key for secuirty.
Please note that Cities XL will be officially released the 9th of October at 1am Pacific time (4am Eastern time).
We'll see you then !
Best regards,
Cities XL Support Team.
It is kinda strange they sent it threw the email and not printed on the Handbook. I better put my email in the safe area! :-)
