NFT games can be just like regular games except tokens are used in them, the NFT's will be a usable assets inside the game and will have different rarities, these are usually tradable on a marketplace. Players are rewarded for playing these games by receiving the native token, these tokens can be traded on an exchange which means the player could then cash them out if they wanted to. With regular games, all the assets that a player collects eventually become worthless when that game dies or the player decides to stop playing. With NFT games, these assets can be sold and sometimes for a big profit, depending on how well the game does. I recommend checking out some of the more simple NFT games if you're a beginner so that you can understand it better. NFTshootout is beginner friendly and has really simplified the tokenomics and gameplay whilst keeping it fun. This game is very new and currently in it's first beta but a big updates is coming in the next few weeks!
