Any Idea what all this is worth?

[Reducible]

I'm currently trying to get rid of this, but have no idea what it's worth, theres Xbox 360 DLC and full games on there. A BUTTLOAD OF THEM, also have an XB1 with forza 5, Dead Rising 3, FIFA 14, and Assassins Creed 4, along with a semi-crappy runescape account thats on there. So any estimates is greatly appreciated to get a general sense of value of the things offered.
