Blake Robbins, who used to work on game design at Roblox, has written an in-depth post on why blockchain-based gaming will never take off.

TL;DR: not only is it likely to be a Ponzi scheme, it's just a really bad idea for basic economic reasons.

The policy trilemma

Narratives can be moulded, but unfortunately crypto gaming evangelists will not be able to change basic economics. The fact that the problem with the Mundell-Fleming trilemma and how crypto games fall on the wrong side of them from a pure game design perspective which ultimately prevent large developers from creating AAA games with open economies as well as ruining user experience is totally ignored by VCs who are funnelling absurd amounts of money into these projects makes me question if they actually believe in the narrative they’re pushing, or if they’re simply investing in token pre-sales and planning on dumping on unwitting retail bagholders.

For the record, I’m not a crypto hater or anything... [h]owever, I just don’t see the application of decentralised blockchains in gaming, there isn’t a need. Putting games on the blockchain will just result in really slow servers as everything would constantly have to be verified by a decentralised database. No one gamer has ever said: “I don’t trust Rockstar to store my data correctly which is why I won’t buy GTA V”. Building games for the sole purpose of “play to earn” or “play to own” means that players are no longer playing games for enjoyment, but rather the hope that they can monetise their holdings. Inevitably, this means that the quality of game experience will drop, as developers focus solely on how to turn every single aspect of a game into an NFT which can be traded. Collectible trading should be complementary, like in Roblox or Counter-Strike , it should not be the whole purpose of a game. You might as well scrap the game altogether, and just focus on making NFT collections like Bored Apes or Cryptopunks. Recreating games to have a similiar culture will not work out.
