In my own opinion , it's only hard forking that can ease the ethereum blockchain, an hard fork should be done for game developers, because this crypto kitties is really disturbing transactions on ethereum blockchain.
What do you suggest???
I suggest you to put around 50 gwei for every of your transaction in the ethereum blockchain. that should have done easily in my opinion. Crypto kitties is disturbing the ethereum network users caused by the crypto kitties users in compete to put the more fees.
