Think back over the last few decades... What sorts of things have we learnt from video games that we previously did not know?
For instance:
We now know that plumbers are usually portly Italian fellows, who like coin collecting and mushrooms.
Plumber's girlfriends (Or rather, "Love interests") tend to almost always have a habit of getting themselves into some sort of trouble, leading to plumber having to go and rescue her... Often...
Despite being a little overweight, we know that plumbers like to play a wide array of sports (Such as Tennis: Golf: Baseball; Soccer) as well as kart racing, board games, and pinball
Plumbers also like to work when on holiday, and have been known to volunteer to clean the streets of their chosen holiday destination.
And they occasionally like to have a jolly good ruck with their mates from time to time as well!
What else have we learnt?
