My husband, I believe, could play computer games for a week on end if he had no other pressing responsibilities. Apparently in Jr. High, he played some games through the night, which I find very easy to believe. He's done it before in college as well.
We have somewhat different priorities. I like normal human stuff like sleeping and eating. He seems to get around to those things when he remembers. I think there have been more nights when I make dinner and put it down in front of him in between his two arms and in front of the keyboard than nights where we've sat at the cute little table in the corner and actually looked at each other.
I knew about this tendency before I married him. It didn't bother me too much because I, myself, am also a geek. I have much more limited tastes and an eventual "your brain is turning to mush, do something else" check in my head, but I've been known to burn several hours at a time, especially on free days. But I digress.
I think that the eventual creation of cyborgs might overcome this problem. I think eventually our electronic devices will become a part of our systems, something combining the idea of tattoos and Bluetooth headsets. A couple of ports in our ears, mebbe a mechanical eye, something like that. What I am going for here, is the implantation of a video game system that will let David get away from his computer so he is less like an invalid when at home and actually able to do something useful. Now granted, I don't see him being able to multi-task to the point where I won't know if he's playing a game, but I was thinking operation somewhere along robot lines, like able to make his own food and vacuum the floor... he won't even notice he's doing it!
So all for turning gamers into robot-like cyborgs? At least the chores will still be done.
(As I wrote this, he discovered he could hook the brand new 37-inch flat screen up to his computer with an HDMI cable and is now playing World of Warcraft at a resolution that would be fine for me, all the way back on the sofa.)
