Digital cats that you can breed, which turn into other unique digital cats and can be sold for more money later.. clogged up the blockchain for a few days, created congestion to the ethereum network and delayed transactions 
We don't want anymore digital cats. We want fast ether transactions, we want fast blockchain in ethereum. We want fast token transfers. That's all. We don't need games in this expensive industry.
Maybe things like this are needed to push everything to the next level in a much faster pace, forcing them to solve it.
