With Axie Infinity, there is a sudden rise of play-to-earn games. At least the way I see is that the core idea is that financial benefits of in-game purchases accrue to the network instead of just the game studio. But most casual games have a very short shelf life of a few years.
At some point, Farmville used to be big then Angry Birds took over then everyone moved to Candy Crush and these days to Wordle. The casual game market consists of games that are fads that will last more than a few years before people will get bored and move to something new. So if a user had accumulated tokens in Farmville or Angry Birds, how valuable will they be today?
Note: professional games are a different matter but the technology is not there yet to build those hard-core games on top of these decentralized networks yet.
