Because ALL computer gaming software is ridiculously buggy and has design flaws. And the computer that you will run it on will invariably crash and burn for no apparent reason.
I learned this lesson the hard way, back when I assumed that, because I had paid money for a game, it should work correctly out of the box. I have NEVER had a game work correctly out of the box with no need to install a patch. Usually, not only is a patch required, but other technical support issues need to be resolved, and even after all of this, the game still has bugs, runs slowly and ocassionally crashes. It is, sadly, a fact of life.
This is why my approach is to, on the one hand, offer sacrifices to the computer spirits to appease them, and on the other hand, display prominently a piece of obselete hardware/software spiked to the wall, so that the computer fears what may happens to it should it cease to function!
Any form of sufficiently advanced technology is indistinguishable from crap (with apologies to the authors of the original quotes)
