There's a lot of focus on the game itself, which looks to be quite complex... nothing like we had before on steem/hive blockchain. The developer is highly involved, and communicates a lot on Discord. The focus on cards looks secondary at the moment, but this might not necessary be a bad thing. Critical will be to find the right equilibrium in the economy of the game... This we don't know at the moment, and not many games managed to find it (the only exception might be Splinterlands)...
