Just to clarify, Metaverse is an umbrella term for anything that is related to a simulated "real world" and NFT is just a part of the broad aspect of the Metaverse. If there's anything worth investing or trading in Metaverse, it's the big boys in the market such as Microsoft, Meta, Apple, Google, AMD, Intel and Nvidia that are continuously making these innovation possible and not those ponzi scheme play-to-earn games.
There is also a good read by Matthew Ball
[1] and Jon Radoff
[2] that explains Metaverse in depth and offers a fresh perspective on how these things actually work.
