I think they're implying causation where correlation exists. I'm guessing most WoW addicts (and there are lots of casual players, who can be fine employees) are simply obsessive types who would be attacking some other hobby full force if not for WoW. D&D, building a robot in their garage, whatever.
For D&D people often create their own stories, and they display their imagination in acting it out (even with pre-fabricated stories, the options for actions are infinite). WoW only allows you to follow actions that have been written into the game by Blizzard. I think it is very different.
However, you are right, employers might not know the difference.
I've never played, but my perception (from what I've heard) is that in D&D one person does the creating and the rest just sort of play. Is that inaccurate?
I really just meant it as an example of a hobby people obsess about though. I don't doubt it's a little more food for the brain than WoW, which I rank possibly below reality television.
One person creates the story, but playing is really roleplaying. The players can conceive the wildest actions, and the master has to come up with a reasonable continuation of the story, often improvising on the fly. I think it is not uncommon that things go entirely different than originally planned.
Sometimes one might even play a completely improvised story, it all depends on the group.
