When I was a kid playing *Three Kingdoms: Heroes of the Ages*, it got boring after beating the game. These strategy games are deterministic, so every replay is the same scenario. Back then, I wished for a game that felt like real life. Later, I came across $BTC and realized Satoshi Nakamoto had created such a game. After thinking about it for 10 years, I finally understood that Satoshi's $BTC game is just a side quest in the *Earth Online* game. If we want to create a game with a truly authentic experience, it has to integrate with real life and become part of this irreversible game called life.
