A huge amount of the blockchain games are tokenized to earn money.

As long as these tokenized items get sold to fund the development and living expenses of the teams this will most likely not change. But if earning tokenized items in games becomes a thing this will definitly change. It is really hard or involves a lot of luck at the moment to earn anything with these blockchain games!

What will happen with ingame economies in the next years could get interesting though, if you ask me.

Sorry for the late response!
