How dangerous are new projects for the real use of blockchain? We have already seen the story of the CryptoKitties, which brought down the Ethereum network. Can this happen again now? What projects can now grow in such a way that will affect the work of the network itself?
I don't have any idea for this because I don't belong on the field but I think they are trying to imply lightning networks so this won't be a problem in the future.
I don't know where you heard about cryptokitties and other ethereum games, but they are not scam.
The OP didn't say that cryptogames are scam, he's just worried about ethereum network congestion again since there are numerous blockchain based games that are coming out.
