There is no economic difference between a freely tradable digital item in a game and an NFT. The only difference is the technical implementation, which nobody really cares about. NFTs bring nothing new to video games, games could have always had primary and secondary markets for items because they own the database and they allow the transaction. That being said, there are plenty of people who use video games for work like people farming gold on wow or selling rare pokemon go pokemon on ebay, mostly to sell to dumb rich westerners who have more money than sense.
