I guarantee they didn't invent anything new to gaming. It's just like all those studies that claim tetris helps with ptsd, stress, lazy eye, postpartum depression, etc. It's just a game. There's nothing that makes this game, or tetris specifically special.
Even though there were a lot of studies on other existing games helping "ptsd, stress, lazy eye, postpartum depression, etc.".
I wonder if they were to be used in some treatment, they would also need to be approved? So Tetris itself wouldn't cost, but the doctor administering treatment gets approval to use the game, and that overall treatment costs the money.
I'm little unsure if any joe blow psychologist is allowed to makeup treatments, or if they go through an approval process also.
