If you haven't already heard or just prefer not to compulsively check Games on Demand after every LIVE update, then we're here to bring the good news. Fable II and Fallout 3 are both available today for purchase and download.
Not surprisingly, you'll find some restrictions, all based on region. Fable II is available in all Xbox LIVE regions except Japan, and Fallout 3, for whatever reason, is listed for Europe, Australia, and New Zealand only. Still, if you check the Marketplace, the latter is already listed for North Americans.
There's already some complaints over the pricing of Fallout down under, and even the American price is higher than a new "Game of the Year" copy from GameStop. Then again, some people really do prefer digital over disc.
