I'd say life and video games are pretty similar:
It's nice to play with others
Typically, you want to get good at it
There are three main motives to actively participate:
To enjoy yourself now
To invest in future enjoyment
To not have to think about it all
And if you think about the “real” goal for a long time, there really isn't any.
To be quite critical in your choice of clothes, food, shoes and so on, but to never put any effort in picking a comfortable mouse and keyboard.
To use a laptop as your primary computer (with no external keyboard, monitor and mouse).
To use a desk and a chair that are not comfortable.
To not know basic keyboard shortcuts after years of using the same environment.
The most plausible explanation I can think of, is that some people are just
completely captured by the interaction with the screen. It greatly reduces their
other senses, especially those related to comfort.
