But blockchain only has "cultural momentum" because of the lure of profits. Is there an example of a popular blockchain project that isn't based on "early buys can get rich by selling to latecomers"? I guess the argument boils down to "it's web3 because it has blockchain, and it has blockchain because that's a good marketing buzzword." Which, fair enough, I guess. That could be right. Blockchain-backed or not, I think it's pretty unlikely that a bunch of competing game companies are going to come up with a system that lets you share items between games. That sounds technically and politically very hard, and for not a lot of benefit.
