This could be among one of my best crypto games I've come across it has a very good user graphics with 3D display with very good attractive interface to attract user.
Being a decentralized blockchain game a user can trade card control his card and sell them to other user, can play games and win card and sell them for real money. Interact with other user, user can have total control of his game building his game from scratch and making it and empire and make fortune from what he built.
A user can play for free but high chance of earning more is by purchasing card with ethereum you can even display your item for sale at the store.
Ethereum is basically use for transaction in God's unchained a user need to have the wallet install and his address need to be linked for receiving and sending, buying and selling card using ethereum.
