I just checked, this is really happening.

Nintendo Switch 2 is cracked apparently, and players are able to duplicate a small square (basically like a small thumb drive or RAM) game cartridge, and then sell the original used, while keeping the copy and playing the copy.
Game stores have no way to check this, neither do players who buy used games.
Nintendo has a registration system for the Nintendo Switch 2 for all games played on it, the system get the code off the cartridge inserted in the game console, connects online to uploaded to the Nintendo main central computer, which checks every single game copy for duplicates. to make sure there are not multiple copies of the same games registration code playing simultaneously on multiple machines.

This is apparently their brainiac solution to piracy of their slop garbage code.
Always online DRM at the console level.

It effectively kills the second hand game market, even for physical media.
GG.
Fanboys will defend this though, and they are the target consumer of this slop so what can I tell you.
Until the slop consumer rises up, they will always consume said slop.
The rule of slop.
There is a SlopBeast born every second ready to consume every pile of slop.
