Ha, thanks for saving me from saying it.
That said, I enjoy my time outdoors as much as any. It is still possible to balance a multitude of activities into your life, after all.
Allow me to give a brief explanation of why Starcraft does not, to use the cliche words of those who are anti-gaming, "rot your brain". It has been described by many as "adrenaline chess": a game which requires the development of strategies, the management of economies, quick reactions, anticipation of your opponents, quick math, and strong decision making. You must also consider hurting the other player's economy, defense of your own base and economy, and a huge number of other things. It is probably one of, if not the most intellectually stimulating thing I do all day (and most of my life is dedicated to my coursework.)
Here's a wiki page on Starcraft strategy. It is also an
intercollegiate sport.
It is very much the evolution of the strategy board game for the next generation.
Now I certainly understand the skepticism of some about video games, they tend to hear all the horror stories from the media of people's lives being consumed by MMORPGs such as World of Warcraft, where people sit all day grinding up their levels simply to see those numbers jump. But to assume all gaming is the same is simply silly.
