This isn't "native" BC for disc owners since you have to download the digital version from MS servers. As far as I can tell any game without a digital version won't be playable. That leaves out a decent chunk of my collection.
Guess my 360 will stay hooked up then, nice try MS.
EDIT: Also what are they going to do about DLC?
This. If it were to be like PS2, Wii, & Wii-U where it can absolutely play all PS1, Gamecube, & Wii games natively using the discs without anything else, then I would be excited.
This doesn't cut the mustard one bit.
