What about physical game disks? I own the disk and can play the game as long as I have the disk. I can also resell or share the disk. Sony once demonstrated this on stage during the PS4 launch.
Digital licenses take away all of this and add the possibility that your licence can disappear at any time.
Physical game disks have maybe one console generation left. Nintendo might keep cartridges around for two tops. The future is basically all digital. When doing his Mea Culpa rounds about Xbox losing the console wars, Phil Spencer talked about how being second in the generation where gamers built up digital libraries was likely too much to overcome.[1] Most game sales already happen digitally[2], and the number continues to rise.
That's very different. In America at least, if you purchase a physical object, you own it. You can do whatever you want with it. It's called the first sale doctrine.
That doesn't hold with games, and that's exactly what this law is addressing. Many (if not most by now, I haven't bought many games recently) physical games are now just an unplayable kernel and you have to download the actual game. If you sell the physical good you are selling a piece of plastic. Quite a few don't even contain a cart or disc in the box, it's just a download code.
Now, yes, you can say "but first sale still holds, you aren't prohibited from selling the object you bought", but most rational people are going to call that nonsense.
