A cross between "Nintendogs" and "Pokemon Go" would be a good way to describe "Dogami," a game that's using blockchain and NFT technology to revolutionize the pet simulation concept popularized in the 1990s and 2000s. In this so-called "petaverse" -- an immersive virtual world for pets -- players will be able to take care of their virtual dogs, groom them, feed them and even teach them tricks.
