They're bad, grindy games. The appeal is specifically that they reward with crypto-tokens that can be traded on exchanges for real money.

It's basically just a way to work around regulations. Technically the game doesn't deal with a real currency, but they give fungible tokens that can be relatively easily traded on third party exchanges.

The financial aspect of these games makes zero sense, as is the whole concept of "play to earn" which should be immediately nonsensical for anybody who has a basic understanding of how the economy works.

Yet another terrible, useless, scammy, pyramid-schemy, economically-inept concept brought to you by the cryptocurrency crowd. But hey, any day now it'll all be worth it!
