I totally agree with your assessment about blockchain games. The problem is often that these games are totally unbalanced. Meaning, the more you invest, the bigger your chances to earn something. This gives a big advantage to early adapters which in turn is contraproductive for the long term growth. You see the long term players accumulating assets that allow them to be stronger than you. For a blockchain game to be really successful the investment should interfer with your capacity to earn. Or in other words investments shouldn't give you an edge towards people who haven't invested. Great post!
I have picked this post on behalf of the @OurPick project and it will be highlighted in the next post! 
Thanks for appreciating my content and thanks for adding that thing about the game being unbalanced. I forgot to point that out.
