In cost of the game itself for sure, but then you'd have costlier price in the disc too.
With the discs the scratches and storage were a bitch of a problem and later games even needed internet connection to activate games running on disc. It had pros but wasn't all rosy either.
It's going to be more convenient and economical just streaming games and renting them forever and then upping the subscription rates and making them exclusive to game stream platforms.
