I own over 3000 physical games and quite a few digital on the 360, I fear one day that Xbox live will be disabled on 360 and I will no longer be able to redownload them in the event of console failure, yet aside real disasters I feel i can access my physical stuff forever.. And if it did go away, could be repurchased at least.
With so many games being delisted, services being taken down, etc, it's a real shame people seem to so happily embrace cloud services and streaming, but I guess i'm old.
