Is The Sandbox a metaverse?

Could you please clarify for me if The Sandbox qualifies as a metaverse? I've heard a lot about the concept of metaverse recently and I'm trying to understand its characteristics. Does The Sandbox offer a virtual world where users can interact, create, and even transact in a decentralized manner? If so, how does it differ from other platforms or games that allow for similar activities? Could you provide me with some insight into how The Sandbox operates as a metaverse and what unique features it offers? Thank you for your help in clarifying this for me.
