How much does Metaverse cost?

Excuse me, could you please clarify the cost of Metaverse for me? I understand that it's a complex and dynamic digital world, but I'm curious about the general price range or any specific costs associated with accessing or participating in it. Is there a one-time fee, or are there ongoing expenses that users need to be aware of? Additionally, are there any hidden costs or fees that might not be immediately apparent to someone new to the Metaverse? Thank you for your time and assistance in answering my question.
