A collector's item for a serious gamer who would appreciate it.  This was a gift for the members of the Original Xbox Launch Team back in November 2001.  It has a translucent green case and has "Great Work! Bill Gates" signed on the top jewel.  It's been packed away and left untouched for a number of years but is still in pristine condition and in full working order.  

Everything shown in the 3rd photograph is included:
  • the translucent green original Xbox launch team special edition ship gift
  • 2 matching translucent green original "Duke" controllers
  • 2 "Controller S" controllers
  • 6 games, including Halo and Halo 2 (only Halo 2 unwrapped to full functionality)
  • power cable
  • component RGB HDTV cable
  • DVD remote and dongle (unverified if working)
  • SE Halo headset (unverified if working)
  • memory card
  • Xbox back pack (this backpack made trips to made Xbox global events but still in tip top shape)
