What's an ideal ETH-based project you'd love to see vs your favorite existing ETH-based project?

I gave a lot of thought to the idea of developing a crypto project centered around it being a video game with the possibility of earning some buck just by playing the game. Ideally, this game would be on par, quality and content wise, with the titles like WoW, Diablo, or Path of Exile, but I know it's far far away from what can be expected at this moment. It doesn't necessarily have to be a new game, but it would be cool if some of the existing ones implemented crypto/NFTs at one point to allow players to monetize the effort they put into the game by selling NFT items, in-game currency as cryptocurrency, etc. Ethereum would be a solid base for a project like this because of its stability and versatility, however, the game would probably have its own coin.

My favorite existing ETH-based project would probably be NFT City Miner. I played the previous game made by these devs (Crypto Idle Miner), and it had me occupied for months, so I assume the new one would be even more interesting, especially considering it would contain NFT buildings in form of owning virtual property. I also made a bit of money playing CIM, and it was actually good if taken into consideration that the game is free.

The second one would probably be Crazy Defense Heroes, but it's looking and feeling a bit clunky.
