Sony has filed a patent titled "NFT Framework for Transferring and Using Digital Assets Between Game Platforms" which could potentially allow players to transfer items from one game to another using NFTs. The patent outlines a system where gamers are awarded NFTs when they earn an in-game item, which can be used across different computer simulations and platforms.

However, it is unclear how Sony plans to utilize this technology and whether users would have to pay a fee to participate. Video game interoperability using NFTs could benefit players by allowing them to truly own in-game items, enhance their gaming experience and provide new income opportunities for developers. However, there are also barriers such as licensing issues and developmental burdens for video game creators.
