Literally a used Switch game in a big, ridiculous bag with a “New” sticker on it. Imagine going into a GameStop with a game in a bag like this and convincing them to give you credit for it as “New”.
Don’t buy online from GameStop. Actually, just don’t buy from GameStop.
Can't say I've done extensive research, and Nintendo would be the first company I would assume would ignore standards, but my understanding is that any half decent charger has a sort of power negotiation to prevent such issue. I suppose if you have some cheap dollar store USB-C chargers laying around it might be risky if they too ignore the standards.
That said, I did have a USB-C PD 65w charger fry a laptop. It was, for sure, the charger screwing up though, I even had warning signs I completely ignored. I miss that laptop, it was a good laptop.
