Why should anyone give a shit about your game?
In other words, what purpose does it serve in your players' lives? Why do they care?
If your answer is, "Because this is an important issue!" or "Because it's GOOD for you to play this game!" then I'd urge you to dig deeper.
Our country is currently putting kids in cages and millions of people skip their daily meds on the regular. Just because people SHOULD care or take action does not mean they will.
So take a minute and try and answer: what's the hook that will draw an onlooker from NOT playing your game to taking the action to play it?
If a game falls in the forest, and no one's there to play it, it doesn't make a sound.
