Honestly bro, you will not get much from it, as for the digital copies they are bound to your account only, and most people think that they are playable on anyones account as long as they are on the HDD. The games that you have are just normal copies nothing like a collectors edition. Also as for your Xbox 360 do you know if it is the basic HDD with 4GB? or is it with 250 or 320GB of HDD, cause that will bring the sell value of your console if you want to sell it. A xobx 360 4GB is now going for 89.99 used.
