One of my favorite physical game creators, Exploding Kittens (and Matthew Inman), decided to put NFC's into their games...

I used to buy hundreds of dollars worth of games for myself and others from them. Ever since I got the email about it, I wrote back to them telling them I'll never buy another one unless they reverse course of that decision. To this day, I've kept my word.

Crypto is bullshit, and I don't want it sewn into the games I play.
