It's not just video games and music. Adobe Lightroom 6 was sold with a perpetual license, but its mapping and object detection libraries did not have a perpetual license, so even though you can run Adobe Lightroom 6 with your perpetual license today, those features no longer work unless you fiddle with your system clock.
Isn't the same happening with video games? I've seen video games remove some music from their soundtracks as their limited-time licenses lapsed.
