The Federal Trade Commission (FTC) is looking to launch an investigation into the practice of introducing loot boxes in video games. In some European countries loot crates are considered to be gambling and are not allowed. It will be interesting to see what the investigation finds. 

If this was for the purpose of putting a stop to it , I'd be happy. 
     -- but this will probably just amount to the FTC making money off it , by having to get companies to pay for a 'license' to use loot crates & put a small label warning on the box or advertisements. 
    I doubt they are seriously worried for the children. 

Good. It's clearly gambling. It is nothing beneficial to games either.
