While I find your observation to be somewhat lacking, I'll submit some info on my 'board, just because I'd like to see what you'll come up with. By the way, a lot of games use the F10 key for the main menu, and the Esc key hasn't been used for exiting a game in years.
My keyboard is a relic from an ancient age, with keys that clack with deafening sound as they are pushed down the extensively long travel. They require great strength in order to fully push down, but they give you the satisfaction and the knowledge that, by Jove, you typed that symbol.
It was cleaned sometime last century, and there is a layer of brownish gunk over everything. What constitutes this gunk, we may never know. Or want to.
There are lazy paths winding their way around the frame, the effects of otherwise unoccupied fingernails scraping off the topsoil. The F5 key is sluggish and the F6 key is unyielding, the result of a few spilled droplets of Ribena blackcurrant drink mix entering the keyboard. Random hairs sprout out from between the keys, and if a person were to look closely they might discover the furry nest that makes a nice, soft padding underneath the keys.
The right shift key is solid, but seems to perpetually be in "that time of the month". It is often late for work after a period.
There is not a single loose key, as the ancient peoples apparently knew more about how to build a keyboard that feckin' lasts than these newfangled folk.
The NumPad is pristine.
