The concept is fine as long as the transaction fee is low enough. The current minimum "gas" fee on Ethereum is something like a half-penny per transaction. That may indeed be too high for practical everyday gaming. But what if the transaction fee drops to a hundredth or thousandth of a penny? What if the rest of the game is otherwise free code on the blockchain, and you don't have to drop $60 for the privilege to play? Then the proposition is not so outrageous. It wasn't so long ago that subscription gaming like World of Warcraft was a non-starter, or mobile micro-transaction gaming was a non-starter, but then both those concepts went on to dominate. There are many possible futures in which blockchain gaming could become viable. It's still early days for the tech. Much is in flux. None of us can be sure how it's going to play out.
