Not sure why me mentioning GTA became the core of your reply, that was the least important part. Any game that makes people en-masse spend $30k to play must be extremely addictive.

> I think that real life is the ultimate game of this kind

Until you give them a game that's beyond street-drug-level addictive, which a game that can extract $30k from a majority of people definitely would be. People would withdraw from real life into the game and that can't be healthy. So I don't agree that it's a pity we don't have such games.
