I am sure it is more to it than that. Or at least I hope there is more to it than that. I w2ould the type of QA person that would go into an area, play it over and over again with different styles and try to find as many things I can "break" then document each "break" and how it was broken by me, and whatever diagnostic code that spews forth if any. Once I get done with that go to the next area and rinse, dry, and repeat, unless there was a more important task that needed to be done.
At least that is how I imagine a QA job to be like.
