In what seems to be a glitch by Microsoft you can go right now to xbox.com, and download Fable 2 for free. I know we only gave it a C, but as Jeff said to me, “free is free.”
I would suggest grabbing it quick before Microsoft fixes the bug. (I’m currently downloading it)
UPDATE: Per @XboxSupport, this is a legit download, but is only Episode 1 of the game.
