I think you might read about Infinity.
Its two different applications.

But yes you need Diamond for that yes.
Although you dont get free games with the game adder.
It says its on your account when you login to Xbox Live

Ya like mr.presice said it not really free games , wow that would be sweet it just makes Xbox think you have the games so you can get the achievements for the games
If you have an rgh of jtag then you can download free games from internet !
