It boggles my mind why anyone would create a game on a blockchain with high fees like ETH has. Eventually you run into the economic problem where the transaction fees are higher than the actual assets of the game, which in turn make the game no longer worth playing.

The only game I got into on the ETH blockchain is Gods Unchained and it is a great game, I have not played it in awhile though, so not sure how it is now. I bought a few card packs but I saw right away the game would eventually be unsustainable because of the fees you had to pay for buying the card packs. Eventually some of the cards would be worth less than the fees you would pay to buy them...

The reason blockchain technology was created is to reduce the cost of moving currency from point A to point B, which the banking system has had a monopoly on since the creation of currencies. When you have high fees on a blockchain there is no more incentive for people to use it.
