The usually-optimistic game designer Jane McGonigal has been thinking about whether those of us who love to play video games will regret it in the end. She keeps meeting people who think gamers will. She keeps meeting people who doubt any of us will wish we played more games.

So...the question she's been asked: "When we are on our deathbeds, will we regret the hours we spent playing games?"

She takes that on in the video here and comes up with a counter-intuitive twist.

This video is excerpted from McGonigal's keynote at the 2012 Games for Change conference.
