Yeah, I’m a parent and I take my kids with me to the gas pump quite often. We shop at Costco and fill up before or after. I honestly don’t see an issue at all, my kids know gas pollutes (I tell them frequently even though they’re in elementary school), and they know why I continue to buy gas (EVs are too expensive, inconvenient for longer trips, and have a fire hazard).
So no, I don’t have a problem with fossil fuels being a thing in games. I do have a problem with advertisements in games generally, and ads marketed to kids specifically. So if this was an ad for a socially acceptable business (take your pick), I’d still be opposed. Keep that nonsense away from my kids.
