# 4.5 The Sustain Economy Model

Contrasting with the simple and raw mining model of GameFi 1.0, we step up the model by borrowing the economy design from conventional MMORPG games:

* Create playable games to attract Web2 players to play and stay.
* Implement a trade-centric economic system to ensure the sustained gains of Web3 players.
* Implement a social system and a promotion reward system to motivate Web3 players to seek new Web2 players.
*
