"If it's a game, who cares" -> Oh let's see... let's say I'm playing a 
game, and then there's a bug (which happens often). What would I prefer 
to happen:

* a small (or big) visual glitch, like pixels out of place, corrupted 
textures, or 3D model of an object becoming deformed, or the physics of 
some object behaving erratically, or some broken animation.

* the whole game crashes, and I lose all my progress?

So Walter, which one do you think I prefer? Me, and the rest of the 
million gamers out there?

So yeah, we care, and we are the consumers of an industry worth more 
than the movie industry. As a software developer, to dismiss these 
concerns is silly and unprofessional.
