Finally, something many of us have been touting for years. With all the anti-game crap (and that's about all it is), it's nice to see a major media outlet posting some research that proves games, specifically ones like WoW, are GOOD for you. Obviously, it's all in moderation. Even water in high amounts can...well...drown you.
I wrote a paper for school a couple of years ago outlining a lot of the research that has proven video games are indeed useful. Many of us have provided anecdotal evidence. The fact is that there is such a heavy bias (which has been challenged by not only gamers, but professionals in the field) that rarely do we see any good news when the reality is there IS.
Video Games aren't a cure-all for cancer, but they have many positive benefits that are ignored or scoffed at.
