Gods Unchained is the first REAL game on the blockchain that people are actually playing right now.
The Game is currently in beta. Userbase is growing daily.
If you ever played Hearthstone you will feel right at home
The game is free to play and you can win pretty easily games with the f2p cards. You earn one booster pack for every lvl up.
But you can also buy cards. Those are the Genesis set cards. The Genesis set is only available in the beta phase. Those cards will probably be worth good money if the game gets a large user base, which is very much possible as it's growing daily and is backed by Coinbase and others.
The cards are currently NOT sellable and NOT transferable, you can sell/trade your cards with the full launch in october.
Also every weekend is a tournament where you play the ranked mode. If you win enough games/you are good enough you are rewarded with GENESIS BOOSTER packs.
Plus currently they are doing a lottery giveaway. For every win you earn 100 raffle tickets. With those tickets you can win rare ingame items and even a mythic card (one mythic was auctioned for $63,000). You can also sell those raffle tickets right now. Currently worth about $1 for 100 tickets (1 win).
At the end of the first season will also be a tournament with a prize pool of $ 1.6 million.

If you have any questions ask in this thread.
I know the first games and deck building is a bit tough if you never played other trading card games but it get's pretty easy and clear after some time.
