I dread to think how bad gambling would be in games without a central hub to complain about it and push back against predatory monetization systems. P2W would be rampant because there are less incentives for people to buy cosmetics.
Though I wonder if society would've even existed or would still have a need for video games. I'd fully expect that by now without the internet we'd either be nuked or live in 1984.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
