VR - Is a user interface. Metaverse is a network built for that user interface.
Historically, we had screen and keyboard based user interfaces, and with it text based gaming like Zork. Then we had screen and controller based user interfaces, and with it games like Pong. At a certain point we got the screen and mouse user interface, and with it FPS, RTS, like Warcraft and Doom. Touch screens were again a new user interface and with it came games like Fruit Ninja. VR now exists as a user interface (although still needs to be improved) and many people love playing Skyrim with it, or Beat Saber.
All of these were mostly local experiences with different (better?) user interfaces.
Meanwhile, each user interface had its own networks that were built on them. e.g. Email is a "first class network" built on the text based user interface. e.g. WWW is a "first class network" built on the mouse based user interface.
The metaverse isn't a new user interface. The metaverse is a "first class network" built on top of the VR based user interface.
