Using the blockchain in your game (i.e. putting your digital currency and assets on the blockchain) is just one way to create an open economy. There are several advantages:

1. Trust mechanism. People don't have to worry about the game platform going out of business one day, making their game characters and props worthless.

2. An open world. People can start building experiences that interact with your assets without having to talk to you, because these are published in smart contracts.

3. Building on the existing momentum, people have come to believe that NFTs have value. By making game assets into NFTs, in-game assets can be freely circulated, and the resulting supply and demand relationship makes game assets naturally generate value.
