In web media, including this magazine, games that include blockchain elements are generally collectively called "blockchain games (BCG)" or "Web 3.0 games."
However, the extent to which blockchain elements are incorporated varies greatly from title to title. Intensive games turn items into NFTs and issue unique tokens. In addition, some games incorporate elements such as the ability to earn tokens through the game, but there are many titles in which the only blockchain element is the NFT of items.
From the perspective of "can you make money," which is said to be one of the attractions of BCG, it is a good idea to be aware of the intensity of the blockchain element before investing, as the intensity of the blockchain element increases, so it is best to be aware of the intensity beforehand.
