There was a time when blockchain games were really scammy, there was a lot of games where you owned like chickens or mining or whatever and you made free money if you want to but very little and if you put in money you could say that good bye because after a while they just closed shop and left. Those times left a bad taste in old crypto people like me, I have been around to know that it is not quite possible to sustain those types of business models and really hard to get funded, cryptokitties is an exception and I can see myself playing that which I haven't and probably won't but I would support their existence at least. With that in mind the new blockchain games are looking like they are better than the last ones and maybe I will be wrong and they will have a good career.
