Now NFT are actively used in games, they are available for all the players. They make games more attractive and fun allowing people to earn money by playing.
NFT was built intentionally for Games and content so that game and content lovers will always be happy when they use NFT while playing and when they have created the content, so it is more for its general use and nothing else.
Not only games, i seen many NFT are for collection hobby, like people in the real life collecting stamp collection based on its rarity. But in the end, that collectting hobby would turn into profit if its sold on higher price.
But games is more practical to use and have earn mechanism, it's also more hyped since many influencer post their earning that motivate another to earn with NFT too.
