Actually there will not be only games on the mainland, but whatever people create can be webshops, showrooms, games, casino, art, university or a bar.
This sounds interesting. Virtual reality is a future such as blockchain as well. Decentraland is became very popular already... May be this project will become popular too.
But how you will monetize this?
I think they will use utitlity tokens to pay for services and purchases inside the VR.
