The addition of the CryptoKitties game to the Ethereum ecosystem has caused considerable network congestion, forcing one particular project, SophiaTX, to postpone its crowd sale. HashPuppies is, in part, being developed to showcase the superior transaction capacity of NEO in comparison to Ethereum network. Other advantages that make NEO an ideal platform for this type of game include fee-less transactions, enabling real in-game micropayments, and the NEO/GAS pairing, which could enable players to generate income within the game without the need for constant transactions.
