After much thought, the only business model that can work in Web3 Game is winner wins from loser, the essence of zero-sum game, not play to earn or win to earn, winner takes all, willing to accept the loss.

In Web2, it is esports, countless events, the winning champion's prize money comes from the promotion expenses of the game project, advertisers/brands, and cultural promoters (local governments, venues, tourist attractions).

In Web3, it is NFT pre-investment, big players hire people to PK, spectators bet, project platforms pump money, smart contracts make fair distribution on the chain, and tokens are used as rewards for project investors and partners.

Then it becomes gambling on the chain.
