This is how game ROMs of old consoles should be handled, a one-and-done digital purchase that makes you the owner of the ROMs to use however you'd like, not through some shady online-only rental service that provides you only with what the company wants with the only means they want, and worse yet, where you don't own shit.
All companies should be forced into such a practice, so that people can shut the fuck about "eMuLaTorZ R pIrAcY!!!11!!!1!".
