I think NFT's in video games will be really fun. Whether that's in DLC or in the form of unique weapons and armor in rpg's or first person shooters. I could see it blowing up big time if game makers get seriously into it. It's why I own a little ENJ.
Here are the games I think will be in the mainstream after a year. AXIE,
