How does sandbox make money?

As a professional in the realm of cryptocurrency and finance, I'm curious to understand the financial mechanics behind the Sandbox platform. Could you elaborate on how Sandbox actually generates revenue? What are the primary avenues of income for this virtual world, and how do they translate into real-world profits? Are there any unique economic models or strategies that Sandbox employs to sustain its operations and continue to grow its user base? I'm particularly interested in how the platform leverages its virtual economy and digital assets to create value for both creators and players.
