I don't think it is healthy to work on a virtual farm all day long, seven days a week, but you might be right when you say that such a game would keep people attached to the Steem blockchain. I have never played games like Steem Monsters or such, because it sounded too complicated to me, and also I had enough to do with my photos, but I think that such a farm might attract many people which would switch from f*book to the blockchain if they could earn some money by playing the game they are playing anyway.
I might be a bit !DERANGED but not only I have a !BEER for you, but also a !COFFEEA which I have bought at the !MARLIANS !shop 😉
