Hello! Ty :)
Yea I remember playing Dragon City years ago, good times.
Almost every game that existed in the past and had some sort of success, can find new things to implement in this new format. It's super exciting to both the player and the developers.
FPS Games could come in with NFTs for their items aswell as rewards on ranked matches, although the level of stress in those would drastically increase
Ty for replying, see you in some Blockchain game hehe
