Someone tried that a couple years ago. It was called Light Nite and it was a Battle Royal game. You could earn sats and withdraw on the LN. They even had Jack Mallers and some other influencers play it while being recorded. It was on Steam for a bit then got kicked off. Apparently, it never got enough traction so they turned to NFT's and minting their own shitcoin for the in game currency. I think it's dead now. lol
