Gaia offers two experiences that allow you to simulate the workforce and real-estate market, and experience a virtual classroom. G-Bucks are the main in-metaverse currency that allows the purchases of tools, land, vehicles, and many more. To speed up the process, purchasing a membership allows access to certain perks. As you continue to grow and buy more and more land, you'll be able to sell the land to others for an in-game profit.
