Base on my observation even without Bitcoin partnership. The NFT is blooming now particularly those play to earn method. Every player will have their own NFT card which the character to send into the battle arena. From daily quest and pvp wins. The players could earn extra tokens with value.
I don't know if there's an NFT develop in Bitcoin or can receive Bitcoin.
The game Lightnite, by Satoshis Games, is doing a great job with this: each character, each accessory, each weapon is a NFT - but on liquid.
