It will end sooner or later, no doubt about that, but I think we can expect around 10 years more for it to last. Will NFT games replace all the other games, is not a question. Surely, it will never happen. The question is, what percentage of the current gamers may switch to NFT games? Will the whole gaming industry be turned on its head because of NFTs, as NFT supporters like to say?
Partially it will roll over (at least I hope so). I see a lot of downsides to NFT, but the situation in traditional games is even worse - I really don't like that when you buy a character/item you don't own it. According to any TOS, this character/item is fully owned by the developer, and you just bought a license to use it. It looks a lot like a scam, but that's the reality of things now. I hope the NFT fixes this.
What is the point of it? I have no idea, but if that is the case, then why are people buying it if you have only purchased it for licensing purposes? I believe you legitimately own it because you purchased it, but if the developer is a con artist, they could easily take it away from you. The way it usually works is if you read the Terms of Service, the dos and don'ts are usually listed there, and owning something is considered publicity because there is a transaction code as proof. Obviously, it isn't worth it if this is the situation.
