Is there a crypto/digital currency video game that is free to play and what you could call fun?

Have and of you had any luck playing video games for digital currently or crypto? Whats your story or advice?

Im looking into crypto currencies which makes me a noob but im looking for something that isint pay to win but instead free and fun, because i dont want to play a game that feels like a chore i want to have some form of fun aswell. This may but shocking but my hardware is low end, i just have a few old devices i would like to give use.

is there such a game like this and can you tell me a little about said game? or could you point me in the right direction?
