re they going to stay on ETH or switch back to Enjin at some point?
From what I read, they were quitting Enjin because the fees to use Enjin were high and on top of that they also had to pay the fees on Ethereum, so what they are doing is to create a similar ERC token standard similar to the one Enjin uses on the mainchain Ethereum, customize it for them and make it more efficient. They also talked about the fact that this decision was also because of sharding, it seems that sharding might be great for DeFi but not as great for games for some reason...
Just about everything in that game required paying gas and that was not addressing the underlying issues they had.
So many game devs doing this... moving right and left shouldn't be a tx on the blockchain, or the action of mining, picking up herbs, etc... shouldn't be a tx on the blockchain, or the number of points you scored in a PvP match, that's not something valuable! Game devs need to start thinking what is valuable and what is not that valuable, only valuable things should be on the blockchain and also, game devs need to look into ZKroolups, Multi party computation and plasma. The scaling solutions alrdy exist, they just need to be implemented.
