No no you're coming at this from the wrong angle. You're trying to attract finance bros, not gamers. Gamers are already growing weary of crypto stuff and NFTs in video games.

Nobody cares about what the product actually is, you have to go in-depth about how you can make money off of it. Many of these "projects" promise guaranteed returns on investments through shares of ingame sales, they say that with your super special early adopter NFT you will get a big advantage on the most valuable exclusive ingame assets which you can sell for a lot of money. Also a classic is that they'll promise the chance for free NFTs for "members" of your cool epic club.

What the game is or what you do in it doesn't matter. The finance bros don't understand and neither do they care. What you need is the promise of money, and that the earlier they invest the bigger the returns when the game definitely releases.
