There is already great project called Revolux for gaiming...
No need for more game coins
I've just had a look at the project and it works completely different.
You play in our servers and mine in-game resources and receive coins based on how many resources you gain. This is why our algorithm is ProofOFPlay and not PoW/PoS. This project is completely different and not been done before.
So if nobody plays... then your coin blockhain is dead ?
