Nope, you've got to have the disk in the drive to play the games off the harddrive. There for a while I thought that same thing too but realized that they wouldn't leave something open like that. So yeah, you have to keep the game and still have the game in the dvd drive. Probably later you can buy the game online and play from the HD... it kind of takes the whole point of having the games on the harddrive doesn't it, but for those with loud dvd drives, it's a big plus.
