As for me Blockchain games are rather interesting time spending if you have a lot of free time and desire to spend it together with some cryptocoins.

I've pleased that I've already overgrown all that and now prefer trading crypto to sitting in all that Blockchain games.
Yes, it is really a very interesting time spending, especially in case you may earn some tokens or coins, it is a double pleasure. But in order to earn something it is better to start playing at the earliest start or may be betta version. But of course in case someone want to get some high profit, playing games nowadays will not bring you a lot nowadays. Although there were some games where it was really possible to earn even a couple of ETH.
