The future of NFT-based games is bright and exciting. As the popularity of blockchain technology and cryptocurrency continues to grow, we can expect to see more and more games using NFTs to represent in-game assets and items.

1. Interoperability: Cross-game NFTs that can be used across multiple games are already being developed. This can be achieved through the use of blockchain technology that enables interoperability between different games and ecosystems.
   
   
2. Virtual Real Estate: Metaverse-style games that allow players to create and own virtual real estate are already in development. These games will allow players to create their own virtual worlds and businesses, and generate real-world revenue through their NFT assets.
   
   
3. Tokenization of game development: NFTs can also be used to tokenize game development itself, allowing players to invest in game development and earn returns based on the game’s success. This can be achieved through the use of blockchain-based crowdfunding platforms or Initial Game Offerings (IGOs).
4. Gaming as a service: NFTs can also be used to represent access to gaming services, such as in-game subscriptions or access to premium content. This can create a more sustainable revenue model for game developers and provide players with new ways to access and engage with their favorite games.
5. Standards and regulation: As the NFT gaming industry continues to grow, we can expect to see increased regulation and standardization to ensure asset quality, security, and transparency. This will help to build trust among players and investors and establish a solid foundation for the long-term growth and success of the industry.
