It seems that blockchain games are becoming a trend with NFT being a fever in the blockchain world as well as in society. It must be said that including games on the blockchain is a good way to ensure there are no manipulations and create unique game items. Now that I know that NFT is being encrypted mainly on the Ethereum blockchain, I think that Ethereum is overloaded to process transactions and high costs are not the solution for users. It takes a blockchain with lower costs and higher speed for NFT to become a popular and sustainable trend in blockchain games.
