If one game is creating such traffic...imagine the scenario when there are thousands of similar games or dapps on the ETH chain.... 
With this issues they can improve the chain. So i think this kind of issues improves the ether. Now they are aware of this issue."They" have always been aware of the issue. It's scalability. And we all know scalability solutions have been being worked on for years now!
I don't understand this thinking. How is everyone just becoming aware that NO blockchain is scalable yet!
