The problem with those games is that they required money to start earn money, wich has changed a bit.
Currently games at Ton ecossystem are making the moment, the fact you able to earn some brand new coins, expecting the listing at exchanges at some point, is what is driven the market, the dream of get rich hasnt gone at all.
Now imagine you being able to achieve that status playing games, investing only your time, sounds surreal for sure, but might happen.
The problem of games still around the huge boosts they do give to Money invested, isnt about skills... i would guess thats one of the issues, the money corrupts all the ecosystem, but without it projects just die... soo isnt easy to choose the best way to follow.
