Darn! My old games won’t work.

Although this is a bummer, a console can only support these older title for so long. This is especially true if legacy support limits the capabilities of newer systems to offer more power and push the boundaries of the entertainment experience. Again, it stinks, but no one says you have to throw away your old XBOX.
