I believe there’s a very narrow link between the specific thing you practise in the game and any real life use of that. Nearly every game is gamified too much to be useful in this way. The n-back games may be an exception.

I would be much more interested in that topic. But like this one, I suspect there is a gray area that no one wants to talk about at all, and for some reason the answer must be black and white. Which makes me suspicious.
