All I can say is that most companies claiming to make metaverse games right now are doing it to please investors and get a higher valuation.
The real customers of a game company are its players. They don't care what you call the metaverse. They want good gameplay and the feeling of being in the flow.Second Life came out more than a decade ago. It failed to take off because it lacked gameplay, even though the technology was already there.
A metaverse game still has to be a game first.
This comes from a tweet by XD CEO @Dash. I don't know what the metaverse is, but I agree with his take on games.
