I would love to play a game built on the Steem blockchain, whatever that is. Unfortunately, there is no such thing now. Despite all the possibilities Steem offers, very few developers are interested in it. Therefore, probably one of the priority directions can be the promotion of Steem with the aim of attracting the interest of new developers who would independently search for what exactly they would like to implement on the basis of the Steem blockchain. They can be motivated by the opportunity to learn how to work with the blockchain themselves, and in case of success of their developments, also by the opportunity to earn.

Your opinion is very correct. A successful game, or some other successful project, would draw attention to the Steem blockchain and demonstrate that it is not only alive, but also able to grow successfully.
