The more games based on blockchain technology the better, though I think it's also going to take some time for blockchain technology to fully adapt to games. Strides are being taken in that direction, but too many games still rely on tokens that require a transfer fee to write to the blockchain or to trade.
In order for blockchain gaming to really go mainstream it needs to be completely slick and transparent. Right now the average gamer would say, "Wait, I have to pay 20 cents to save and use that new legendary item my character just found?" which would only serve to discourage them from participating in blockchain games.
When blockchain gaming has built a large and robust infrastructure free of transaction fees using technologies like Hive is when mainstream games and players can really start to adopt the technology.
Yes, I agree, the transaction fees are certainly a turn-off for many players. But some would argue that they're necessary to ensure the blockchain is secure. Others think fee-free dPOS chains like Hive, EOS, WAX, and Ultra are the way to go. We still don't know how things will play out, but hardcare blockchain gamers will likely stay with Ethereum. When it comes to attracting the mass gaming market though, Hive and other EOSIO chains could very well win out.
