I’m not sure what point you’re trying to make. Pretty much 100% of games today aren’t trying to push for decentralization, and we haven’t abandoned them for an NFT based MMO because the concept for gaming is extremely new, but there’s a reason people want MMOs backed by a blockchain, so to basically say it’s useless because nearly 100% of games are part of the status quo, therefore such changes are useless (or unwanted) is not a valid reason in my opinion. Just because a status quo exists, doesn’t mean the status quo shouldn’t be changed.
A blockchain doesn’t stop devs from spawning objects — that’s not a concept that blockchain is trying to stop or intends to stop, but at least we’ll be able to audit exactly how many exist in the world to determine actual rarity and freely trade the items outside of the ecosystem.
