I just got the game a few days ago and I have been through all the campagnes.  Am I missing somthing or your reward for beating it is a medal?  I feel a little let down  

   Don't get me wrong I love the game... but I'm moving on to X2 the Threat and Freelancer.  I will check the Boards often to see if there is a cool add-on.
