Great idea. When I learned about the Steemit, I was surprised that you can write posts and comments, and get paid for it. And my next thought was: "The next step is to pay for that you are playing a PC games." 
And now your turn 8)
When I read your post, I immediately remembered Heroes of Might and Magic game 8))) 5-8 hours game and "The winner takes it all!" 
Please don't forget me when you will realize this idea 8))))))
