@Q.U.I.N.N. media costs is probably the shined up version of what that cost tree looks like.  Think of storage, transport, logistics, etc too.

The beancounters decided at some point that the vig of digital storefronts was a better deal than the physical infrastructure game.  It's not impossible that the math starts changing on that calc.  If 1 game is 10%+ of a consumers budget for the month that starts getting hairy.
