Protest the game maker
By all means pressure companies to drop or change objectionable products. You may well succeed. But for a lasting fix, it’s vitally important to reach out to those who see nothing wrong with buying and using that product. Show them why it’s harmful. Show them why they should have no part of it.
Do not expect a willing audience. You will most likely have to whittle away over time. You may have better luck with the rising generation while leaving to attrit those who don’t get it. Either way, it is worth the effort and the time.
