Yeah, I read about the casino problem in the news of casino-casino-casino.net.
I personally think it was the right step to ban it in many countries because gambling addiction is a very serious problem that can ruin whole lives. So if young people are excited about GTA Casino wins they might want to go in a real casino consequently and would lose all their money. GTA has so much more to offer so I don't think it's a pity to not have a casino.
