Paleblue, while others have already provided your answer I did want to confirm that as the game's page says, it comes shrinkwrapped with the CD stuck inside the manual. This is standard for all our games that come with a decent sized manual (e.g. you'll find all the ProSIM titles are like this) while games that have smaller manuals tend to come in DVD cases. Believe me, there is no way that Dom 3 manual is squeezing into a DVD case anytime soon.
We don't do boxes because we don't put anything on store shelves so it's silly to waste cardboard on something that will end up trashed 90% of the time anyway. If you're worried about the CD coming in a paper sleeve finding jewel cases is pretty easy, and chances are you might even have an old CD or game that you don't care about anymore that could house your CD. Personally over the years I've actually gotten rid of all my jewel cases and moved all my games to paper sleeves. Saves a tremendous amount of space and weight!
