So you would buy a video game that is meant to be played and never open it but instead buy a second copy of the game to play?
That mean youd buy a new car and not drive it but instead buy a used one to drive?
Bad analogy. A new car is used once it's off the lot (and some might argue earlier than that) and loses its value quickly. A new (sealed) game can go up in value, and likely will in this case. A used car still has value whereas a digital download does not.
