Steemmonsters is really a great game and it's proving itself to be very sustainable and profitable(unlike others).
No other game that I know on steem has given much rewards like steemmonsters while not compromising the buget.
And it's free rewards based on the time you play it, each card can be sold and make some bucks of it.
Other games developers should learn from it and make steem a sustainable network with revenue for everyone.
