The esrb is actually owned and run by many of the publisher company's like EA and Activision It all started with mortal kombat 1 on snes and Sega I'm sure you could find it in Google Basically the law makers were gonna stop violence in games so esrb was created to (before law could get involved) rate games with the system we have now The reason we don't pay with real money and have to buy silver first is so it's classified as simulated gambling, it's effectively a loop hole so they can still market to a larger crowd and not have to only market to adults
