Where can we buy metaverse land?

Excuse me, could you please clarify where exactly one might go to purchase land within the metaverse? I'm curious about the specific platforms or marketplaces that facilitate such transactions, and whether there are any particular considerations or factors to keep in mind when making such an investment. Additionally, I'd appreciate it if you could elaborate on the legal implications and ownership rights associated with owning virtual real estate in the metaverse. Thank you in advance for your insight.
