That's not a new concept, but sadly (and as far as I know) those never took off? The Sandbox, Decentraland, and many gaming projects ended up dying as everything else in crypto that's backed by nothing but hype.
IMO, the only thing that would make this take off is big existing studios building AAA games with those technologies. Until then, I don't see it happening.
You missed the RONIN token and their blockchain. At the peak of the gaming season, it used to be worth $4B+ in FDV, and right now, it's at $60m lol
There was a time I believed that gaming tokens would do very well in crypto, but as of right now, it's safe to say all of the top gaming projects from the class of 2021 are all dead. They might see a bit of upward price action, but that's about it. Just like NFTs, I feel like the gaming concept is dead unless they come up with something innovative other than what we have seen in the past.
