Good game, but the fee to transfer ETH too big! I do not think so reasonable, as a game!
I have play a few hours on Cryptokitties with ETH and I cannot still understand the concept of it exactly and it's too much painful to me for trading/playing on cryptokitties. What is the value of the kitties?
How could you say it is a good games? As you still didn't understand the concept and goal of it. Actually, it is just to make money and to clog ETH network. They actually did success. But if ETH value slip, they are going to lose money.
